Well... I want to play minecraft with some friends of mine and I can host and run a vanilla server but nothing modded. When I open the "start.bat" this happens (see picture) when I click on ok, the commandpromt closes and nothing further happens... when I open the Forge 1.12.2 ~~~ universal the server wants to start with 250 meg's but with 250 meg's it wont even create a world, to play in... I tried reducing the amount of mods from 21 huge mods to 17 smaler ones. I googled for solutions for well over 9 Hours straight (hours are counted) and feel like I visited every page about forge server ram problems.
If you need some specific details let me know.
Please help me quickly, best regards from Austria!
