Subject: [PATCH] Fix dangerous end portal logic
|
|
|
|
End portals could teleport entities during move calls. Stupid
|
|
logic given the caller will never expect that kind of thing,
|
|
and will result in all kinds of dupes.
|
|
|
|
Move the tick logic into the post tick, where portaling was
|
|
designed to happen in the first place.
