Are you previewing the same layout? If you are switching between different windows in C2 and then press F5, you may be running different layouts.
So the problem is with two text objects missing? Run the game in Debug Mode, see if these objects exits, check their position, visibility, etc.
Check if inst_Show variable is true, maybe it gets reset to false by some other event..
it is the same layout i've made sure of that, I just switch between the menu layout and the menu event sheet tabs. I checked in debug and the times that it doesn't show the text the inst_show is not being set to true. But it is not every time. To get it to set to true I either just have to close and re-run or switch from menu layout tab to menu event tab and run or vise versa and then it does get set to true, but again if i close and re-run from that it then does not get set to true. Running it in debug mode from the menu layout tab it doesn't do it every time, sometimes i can close it and then re-run the preview and it will stay two or three times but on the third or fourth time it doesn't set the inst_show to true. When the sprite fonts aren't showing and it is not setting the inst_show to true the sprite fonts do still exist
Tried it with the same setup that i have for another slide in menu option and it doesn't seem to have any problems with that one so it seems to be localized to just the new one, the lightning skill menu
