LineTrace (BP) sometimes not work with exact same collisionbox although box is there. Linetrace just goes through the box

having a done a maze where pawn does a linetrace by objects (also tested with “profile”) to check if a collision box is in a certain direction. user releases a button and has 4 of them for each direction. if he releases wrong button he gets error message ui with timeline for some seconds. after that he can try again. this works but 1 of 100 the linetrace does NOT work although the collision box is there and is rendered. it just does not get the collision.

  • object profile is correct and is never changed
  • there is no other collision
    you can hit the right button again and again, it just does not work.
    sometimes you hit the right button (e.g. 30times) and after 31 hits it just works again as the collision exists.
    someone any idea?

i now know that it is related to performance of the pc. as a hack i connected a scene object to the collision box which i move every tick. it is a workaround but substepping or working with max. fps did not work.
