struggle to set a basic teleporter

[vuskor]

Hello all, I have a curious behavior on a very basic teleporter;

As you can see, it have been set very basically.
It lead to a teleporter with tag 2.



So far, everything going according to the plan!
When I test the game, then a very strange behavior appear. At start, I can teleport, but after some reasons I don't handle to define, it become totally impossible to teleport. Impossible to walk on, the player still locked against the vector and can't cross it whatever you try. True for every sides.
I have absolutely no clue why it's happening. If someone experienced that before, I would appreciate the answer!

Update :
Seem I "fixed" it; I changes the tag for the sector formed by the four vertices forming the teleporter; Seem it fixed the issues!
