We found a very strange bug with missing \ incorrect colliders. We run game on a group of test users and with replay system we caught several strange situations Test case 1 (No changes in code between screenshots, 100% reproducible error) All colliders trigger Bonus \ Walls \ Monsters all have static collides. From character we create Ray (sphere collider cast) Ray not see one wall and some monsters But some monster stay visible for ray On second turn (monster move) All work fine If we change wall from static to kinematic (for test): walls detected, but some monsters not detected. If we remove from scene two bonuses. All works fine. Why this may happen?
