Gremlins happened whenever P_TryMove and P_SlideMove/P_BounceMove disagreed on what an object collided with. When TryMove said you collided with a line, but P_BounceMove said that you didn't, then you'd get gremlin'd. To fix this, P_TryMove now can edit a struct to contain information on what it collides with. P_SlideMove and P_BounceMove no longer try to detect walls on their own and now requires this result from P_TryMove. If a slide/bounce is needed without moving the object, then you'd want to use P_CheckMove to get the result. Lua is not supported right now.
