(Not So) Simple Menu

This is an in-game limitation - having too many HUD or In-world texts, which often change their contents, can greatly lower game's FPS even on powerful PCs

This can (very rarely) happen if you've been using the menu extensively. Unfortunately, I don't know the reason for why exactly this is happening, but once it does, after toggling it off and on the menu should be back to normal

Workshop was never really designed to support such advanced menu system. Having multiple players use it at the same time or quickly opening submenus and going back is very taxing for the server. Make sure to limit how many players are using it at the same time and/or give it a second or two between opening and exiting submenus

If you enabled the Repeat setting or you've added Jump to action action, make sure that you also have at least one Wait action added in between too, especially if you have a lot of actions added in the Timeline

There's an internal safeguard that disables these actions and this setting if there's no Wait action added somewhere in between in the Timeline and the flow would end up in an infinite loop. Otherwise it would end up crashing the server

If you use toggle crouch, make sure to press crouch again after opening the menu, even though your hero isn't crouching. Otherwise the game will keep seeing the button as being constantly pressed - even though it isn't - which stops every menu action from executing
