Steps to reproduce Go to any region. Crash the viewer in a way that it doesn't properly send the logout message. Attempt to log back in. May take a few times, but once you get it, it's hella annoying. The issue Once the bug is triggered, the agent in the region will eventually disappear, especially so if the agent tries logging back in. Once the agent does log in, the region will refuse to grant capabilities to the agent (Login server passes the simulator address and seed caps, but the seed cap will return 404). This will last for more than 15 minutes where the agent is unable to log into that region. Work arounds To just log in: Log into any other region (Home, etc). To get back into the region: Log into any other region. Enter the region that you crashed in (Sometimes this may have a stalled TP which results in a disconnect). (Observation) Observe that no mesh loads, as the capabilities are returning 404 for the region. Log out (Gracefully!). Log back in (Capabilities will now be granted in that region because of the graceful log out).
