[MIRROR] fixes jps mobs occasioanlly pathing forever (#2205)

* fixes jps mobs occasioanlly pathing forever (#82874)

## About The Pull Request
if MOVELOOP_NOT_READY gets passed once through the signal (which can be
often), the failure increments gets reset back to 0 and starts counting
again. this can cause the increments to never reach the max failure
threshold so itll keep checking forever. i saw some mobs get stuck
trying to reach an unreachable target because of this

## Why It's Good For The Game
