I'm having issues joining my server hosted by apexhostingmc while epic fight mod for 1.16.5 is installed. As soon as I join, it instantly kicks me/crashes. I'm using a modpack, but these mods are all compatible with each other on singleplayer, including epic fight mod.
Here is an example of the crash report. https://mclo.gs/HhLQQ2A

EDIT: Sometimes it crashes before I join, due to a ticking entity caused by this mod? Here is the crash report for that. https://mclo.gs/vqbIQsw

I updated the server's version to 16.5.12, and it crashed a few seconds after launching. Here was the crash report: https://mclo.gs/ANXEvnW

EDIT: also idk what is causing this, but when i log into singleplayer, everything is tiny: https://streamable.com/puat1g

Please try in 16.5.12 version. There was a massive memory usage issue when installing many other mods and it was solved in the latest.

It looks like your environment variable for Java is set to 16. To launch the 1.16.5 server, you have to set it to Java 8.

I set it to that version of java, and I received another crash with ticking entities.

apparently this mod runs smoothly on 1.17.1, but whenever I try to host it with apexhosting, it crashes; here is the log report:

I got it running by using a previous version of forge,

but I ran into an other client-sided bug which makes everything my character hold tiny, and I've tested this with the mod alone without any other mods, and it's still occurring. Here's what it looks like: https://imgur.com/a/59Br7gp
I'm positive this is a client-sided issue because apexhosting didn't have this happen to them, I cleared my config and tried running this mod on 36.2.0 forge for 1.16.5, but it still gave me the glitch, and I also tried using previous versions of the mod but the glitch still occurred. Any reason why this glitch is happening?

Are there any other mods you're using now? Some mods have incompatibility and it looks like this. (e.g. Wizard Staff)

Removing wizard staff seemed to work, thank you : )
