One of the part of my code controlling the bullet collision in my game is messing up, and I can't work out why. The only answer is a bug in the engine.
The first part clearly states to ignore collisions with sensors, and action an effect if hits a tile. However, ingame, the bullets ignore tiles and hit sensors instead.
I have checked an old version of the game and no changes have been made to bullet collision
Ignore the part after the always script, it was a failed attempt to fix this issue
