Work orders could not be created for some buildings: On roughly one building in five, every trade (Gewerk) you could pick was rejected with a message saying it did not match the building's type — leaving no way to create a work order at all. CK was applying its own copy of a rule that only D+ can answer correctly. It now asks D+ directly whether a trade is permitted for that building, and where a building genuinely has no trades available it says so instead of asking you to pick a different one.

Gustav could pick the wrong building in a property split for billing: Where a property is divided into billing units that share the same name, number and address, Gustav had nothing to distinguish them by and could attach the ticket to the wrong one — which then left the D+ ticket without a proper assignee. The billing units are now clearly marked, and a ticket that lands without an assignee is reassigned to the team's fallback.

Emails were documented into D+ more than once: Retrying, re-importing or re-linking an email created a fresh document container each time, so the same email could appear several times on one ticket. CK now checks what is already documented on the ticket before uploading.

A document rejected by D+ was reported as filed: When D+ refused a document, CK recorded it as successfully uploaded, and Gustav reported the same. Rejections are now reported as failures, and when a container is incomplete the specific documents D+ refused are named.

Common-area issues attached every resident in the building: A complaint about a stairwell or lift could pull the building's entire resident list onto the case and onto the D+ ticket. Only people actually involved are attached now; a common-area matter is linked to the building alone.

Cases that had been archived could still be suggested: The matcher could propose linking an email to an archived case, and an archived case could be imported into. Archived cases are now excluded, and if you do want to use one you are asked to unarchive it first.

An archived case made its email impossible to review: If a suggested case was archived, the email showed as needing review but displayed nothing to review or dismiss. Archived cases now appear in that list, marked as archived.

Accepting an ERP ticket suggestion could duplicate documents or fail outright: Accepting the same suggestion twice created duplicate documents in D+, and accepting a suggestion for a ticket that had since been linked elsewhere failed with an unexplained error.

An owner could be described as a tenant: When CK assessed the legal context of an incoming email, it inferred whether the writer owns or rents from indirect clues, and could label an owner as a tenant. It now reads the unit's actual occupancy rights, including the person's role and the period it applies to. The "New Communication" report email also names each occupant's role and its validity period.

Emails could be lost when an attachment could not be read: A single unreadable attachment — an empty or corrupted file — could stop an entire email from being processed, with no case created and no visible trace. Such attachments are now marked as unreadable and the rest of the email is processed normally. The attachment list shows that the file could not be read, rather than leaving the summary blank.

Cases containing certain emails could not be opened: An email with no subject or no message body, such as a scan sent without any text, caused the case to fail to load entirely.

Declining an email import could fail silently: If the message could not be marked in Outlook, CK still reported the decline as successful — and because the marker is what stops the email being collected again, it could come back and create a duplicate case. Failures are now reported, and nothing is saved unless the mailbox update succeeded.

A reprocessed email showed the wrong notice: An email that had been reprocessed and not linked showed the generic "not linked to case" message instead of the notice explaining it had been reprocessed. The German wording of that notice was also corrected.

ERP ticket numbers were invisible in dark mode: Gustav writes ticket numbers in a highlighted style that rendered white on white in dark mode, hiding exactly the part of the answer you needed.

Emails deleted or moved while being processed: If a message was moved or deleted in Outlook while CK was working on it, processing stopped — and could stop the rest of that batch too. These are now skipped cleanly.
