InitPostEntity hook does not run on Linux clients in servers

[textstack]

Details

If a client on Linux is playing on a dedicated server, the InitPostEntity hook never runs. It does run for Windows clients, and it does run for Linux clients in singleplayer.

Steps to reproduce

1. Have a clientside lua file on a server that adds to the InitPostEntity hook
2. Join the server on Linux

I am a bit confused. The InitPostEntity hook does not run for each player. It runs once, after all map entities have spawned. It usually runs before any player has even connected to the server, and I have definitely never heard of a differing behavior depending on client's operating system. (Again, the hook has nothing to do with clients entirely)

Perhaps you are looking for PlayerInitialSpawn?

I'm referring to the client realm. The hook is listed as shared on the wiki, and it does indeed run in the client realm for Windows users and for Linux users in singleplayer. It does not run on Linux clients when joining a server.

It seems to be working perfectly on Linux in my testing. This is NONE beta client on a NONE beta server, but I have also tested x86-64 client on the same server, it works as expected in this case as well..

After testing more thoroughly, I realized it was an addon breaking the hook without me noticing. I was convinced it was a base GMod issue because someone else claimed to have the exact problem I did while on Linux, I guess the hook was breaking with an addon for them, too. Sorry about that.
