bots are unable to pathfind if the target is on bridges or their blueprints. 

also if the bot thats trying to pathfind starts on(not in the blueprint, not one of the ramp bridges) one then it cant 

also remember gates. bots who are in gates are forgotten by all others.

Ok your first bug first. What steps are you taking for this?

A way to solve this is to have the bot move to next to the bridge, then walk on it in which it will do anything it needs to do on a bridge.

1. put recharger bot on top of a flat bridge. not one of the ending segments. it cannot pathfind its way to a bot from there.

2. put a bot on top of a flat bridge surrounded by bridges. no bot can pathfind its way to it.

3. have a bot lose power in a gate. recharger bots cannot pathfind to it.
