My server crashes when I try to light a nether portal with flint and steel.
Mod works as intended on my single player world. Client has optifine, optifabric, hwyla, voxelmap, orderly, roughlyenoughitems, and autofish installed as well. I can link versions of any of those if needed.

Here is my crash report: crash-2019-08-29_04.32.21-server.txt

Here is my server log: 2019-08-29-7.log.gz

Thank you for any help!

I also have this issue. Portal lights, I can see the default red fog on the other side, and then the server crashes. No chunks load before the server fails.

Try 0.15 version and see whether this issue still exists
