Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting The RAM goes crazy

Hello everyone !
As the title said, the RAM usage of the engine (in the definitive edition) goes crazy. In less than 1hour it can go to 15 until 50%. I was a little bit ok with that because I used to make small GM maps...but I did a big map and god, it would be impossible without rebooting the engine every hour. The strange thing is that the normal version of the engine is fine and doesn't have this problem. Plus, I have a good enough computer to run it. So please help me :'(

Here is my computer configuration :
-GeForce GTX 1660
-Intel Core i5-4460 CPU @3.20GHz
-12G0 RAM

PS: note that the normal version was working fine with a lower configuration (and sorry for my bad english)
