Summary0004238: Players with INVISIBLE flag cause monsters to desync
DescriptionMonsters don't react to players with this flag, however clients think they do, and so monsters start moving every now and then and do weird things, but they are actually where they are doing nothing on the server's end.
Steps To Reproduce- Join game in survival.
- Observe in countdown that the monsters are moving around but aren't actually on the server's side.
- Happens in regular gamestate too, after countdown.

It also seems that clearing the said flag afterwards doesn't make the player visible again.

The example is also "broken" offline though and also in GZDoom 1.8.6. The difference is that the monsters move east online due to some very old bug with monster targets that was never fixed. Though I will say that the flag sync seems to be broken since they still do the wrong target checks online.
