• What did you do? Sent an artillery wagon to a place to shoot at nests

• What happened? Artillery wagon takes a long time to find a target and start firing. Sometimes this is a few tens of seconds (typically 10-15), sometimes it's a minute. If it's really close to nests, it's almost instant.

• What did you expect to happen instead? Artillery started aiming almost immediately.

Apologies for the bad audio, I didn't realize I had multiple microphone sources on at once.

Thanks for the report. That's working as intended. The cannon(s) scan 1 chunk per tick in a circle starting from their current location until they find something to shoot at. The bigger their range the longer it takes to scan that entire range.

IT's limited like this so it doesn't lag the game as they try to find things to shoot at.
