I've added something to the code like this: the bots should check if the ladder is used by another bot or not (to prevent stuck bots one climbing up and the other climbing down). What does it have with this teleporter? Well - at the first look - nothing, but if You put that flag for the waypoints at both end of the teleporter, they shouldn't stuck. Unfortunatelly that crap sometimes is not working. Dunno why the people don't write yet any bug report for that - it seems I really miss good beta-testers
. It's not working if both bots (from opossite sides of the ladder) simultaneously notice the ladder is used by another bot - no one of them wants to pass the ladder then
