Okay, so finally I found the solution, thanks to Ruby I think. Really appreciate your help as well <3
So basically, I was able to figure out I should delete them manually, AKA from the map's folder in the material file and that actually fixed it perfectly. Thank you guys so much!
Also, Silver, if you made that map maybe you should try what I did as well. Just go to media>terrains and the folder for your map then go to <Mapname>Objects.cfg then search for the name of the cave. You'll see all sorts of coding like this for example...
[Nature Stuaf 1/Pumpkins]
5120.82 69.6157 2948.42
5176.14 69.3838 3023.21;1 1 1;0.843063 0 0.537815 0
Nature Stuaf 1 is the object group, Pumpkins is the object name. The numbers there you have to erase alongside those two, to fully erase the object basically...
...So yeah. ^^'
