[Fixed] How do I get my global variables back?

I was attempting to fix a problem regarding map creation causing infrequent crashes in my latest mod, Call of Duty: Zombies. When I attempted to reduce said crashing via removing a set global:round block and directly changing its initial value from 0 to 1, all other global variables on my workspace disappeared. Because of this, mod has practically ceased to be (because at least 75% of the game is dependent on these variables), with no clear way of getting any of it back, all because I changed the value of the round variable (not connected to 99% of the variables). If anybody could please help me with my major predicament, it would be greatly appreciated. I have tried reloading the code, clearing gradle cache, deleting the gradle folder - all to no avail.

9 months of progress on this mod - half outside MCreator - gone in a second.
