@awesomerobot thank you! Pardon me, it seems I didn’t upload that.
I tried to re-create the issue and couldn’t consistently reproduce. Ideally it would have simply saved the message as a draft.
If this continues to happen I’ll see about pulling logs and doing deeper analysis. Hopefully this error is enough to help here somehow.
The one I can reproduce: create topic, add tags, switch to private message, can’t post a private message with tags. Low priority bug though
