So, dev user, I can write and understand ubot pretty well. I've been using a particular code that works ... fine ... until it suddenly doesn't. Nothing special, just some form filling, that suddenly stops working. After a restart, it works again. I've tried the 5.xx builds that are lauded as stable, same issue. Newest build, same issue. Is there some sort of debug that I can submit to the developers or is this just a "it mostly works" issue?
