Having many actors / lag breaks opening the buy menu

[vatrat]

Describe the bug
The radial menu partially breaks with too much game lag. You are able to switch weapons and choose AI modes, but not open the buy menu or form a squad. This seems to be a result of the GUI timer being dependent on a fast game.

To Reproduce
Steps to reproduce the behavior:
Any gamemode
Spawn in large numbers of actors, whether all player-controlled or mixed between player and ai.
Attempt to use the radial menu to open the buy menu or create a squad.
Upon selecting, nothing happens, regardless of how long the cursor is left in place before letting go.

Expected behavior
Using the radial menu to select a function produces that function or some effect

Screenshots

Additional context
This is great! I had no idea CC even went open source!
