Okay so at first it worked perfectly - it loaded up all the mods and etcetera without any issues. But it was lagging a lot so I googled how to allocate more ram to the game and came across the .bat file information.
So I made a .bat file which currently says
"java -Xmx3G -Xms3G -jar minecraft_server.1.12.2.jar nogui
pause"
When i did Xmx1 and Xms3 it had an error so I did both @3. However once I ran the server on that it loaded up the world but didn't load in any of the mod components - I.E. not spawning mobs related to the mods and etc, but they still showed up in JEI as things that existed.
So I closed it out and ran it on the default one again but the issue was the same lmao. So wondering what happened? It's not loading any of my map's entities after doing that .bat thing, even after I switched back to the regular .jar starting of the server.
& Two tries after that it just crashes without starting up at all.
Here's the crash report?
P.S. This is my fris ttime doing any of this, I'm just trying to make my custom map on a server just so I can add some plugins that can't be used in solo player mode. I made/edited the map in single player mode up until this point.
