I created a new project to verify. Here are the repro steps:
Create new project from ATBTT plugin on Epic Games Launcher, Unreal 4.24
Open MainMenu map
Set Players in play dropdown to 2
Set dedicated server
In dropdown, use “Play in editor window PIE”
In one window, change the map to Example
Press Done, the map will start waiting for players
On the other window, press refresh, and join the game when it shows up
You’ll see this:
In console you will also see all the script errors for grid manager ref.
On the client, none of the units are placed correctly.
In my game, it’s identical except I have ability system enabled. The abilities HUD does not show up for the connecting player.
In my game I’m trying to modify as few ATBTT things as possible, so I’m 99% sure this is a plugin issue.
