I noticed when killing bots in Azek last night using a Rag3 that my swarms would sometimes not lock on to the target and would just fire straight. It kept happening and seemed the solution was to change to another target and back again. It was quite frustrating and seemed to worsen the longer I was there.

I also experienced this earlier in morning

yea it happens, but usually when someone is doing something to auto lock onto the bots upon undock from a capship. it happens to me when i do the levi as i auto undock and autolock the queens.. (the bounding box shows them targeted, but they are not) and the solution is as you said, retarget them.

perhaps a higher delay on target lock if using scripts or use an appropriate event provided there is one, to determine you have completed undocking sequence then a delay on top of that.
