For the last several CtC convoys, both Itani & Serco, the Assault class escorts (TyCorp and Prosus) never launched. They show up on the sector listing, but the ships never undocked.

Also, the Serco convoy has a couple times never jumped out of Sedina L-2. The transport undocks, flys out, and never jumps.

I noticed that too last night but it does not seem limited to CtC.

I shot at a Xiang Xi guard to see whether this would change anything. This had no effect on the convoy. The strike force came out, without two seekers that were nevertheless on the sector list. So it seems that the bug is affecting various kinds of bots.

Hmmm... on further observation, it seems that for the CtC convoys, only the first two ships to exit actually launch; the rest of the convoy stays inside. Sometimes that means the transports themselves don't launch.

Also I think CtC is confused about when peak is. Around 6:00 PM MST (tail end of peak), transports were carrying 9 units; at 4:00 AM (not anywhere near peak), they had 19.

Ok, the CtC bots and strikeforce bots and all other bots that launch from stations weren't working properly. There's a launch queue to prevent bots from spawning on top of each other. The queue was ignoring all bots in it, so the first N bots would launch fine, where N is the number of immediately available launch bays.
I fixed the problem for the next server restart.
