@SycoZ Does your room scale has been correctly done in SteamVR? Try also to delete and re-apply the navmesh. If not you can pm me I’ll probably find the problem in no time!
I would do some testing just to be sure that the teleport splines are correctly deleted and they are not accumulating; I would also check for any memory leak / garbage collection.
I’ll do some further test on that. If it doesn’t go away, I can check it.
