Summary0002143: Desync: A_LookEx fails entirely on client.
DescriptionA_LookEx fails entirely during network games, desyncing gameplay:
When Offline/Server, A_LookEx does what it's meant to do.
When Client, A_LookEx does nothing. Cue desync.
Steps To ReproduceRun attached wad.
When server, zombieman blinks and spawns two archvilefire actors, then disappears.
When client, zombieman spawns one archvilefire. (the latter is SXF_CLIENTSIDE)

When server, doomimp behaves as default.
When client, doomimp will desync, standing idle on client while behaving normally on server.

Desync will end on serverside change to actor, ie state change. (attacking, in pain, dying)

 When the server informs the clients about the relevant outcomes of a code pointer, the client should usually jump out of the pointer at the beginning, see A_Look for example. Did you intentionally not do this for A_LookEx or is this just an oversight?

 Oh right, the client should probably break out of that. I'll address this soon enough.

 That is addressed now.

 Are you sure that (unlike A_Look) A_LookEx doesn't need the stealth monsters stuff on the client? I guess that this is either needed in both functions or in none of them.
