Me and a friend created a modded server to use through server.pro, and installed a modpack that is called Fufu's Modpack (I put the pack together) and properly uploaded (we think?) all the files. However, when we play, some people more than others, end up getting their screen wiped to minecraft-sky-blue, and then crashing with a report saying :
The game crashed whilst rendering entity in world Error: java.lang.IndexOutOfBoundsException: Index: 75879, Size: 0
And the crash logs depict this:
(Pardon the poor images, It was the only way I could find out how to show the crash log)
It commonly happens when people die, join, or sometimes randomly when like, killing a horse or such.
Could it be some mods aren't compatible? Everyone is playing through the twitch mod tab. It would be very much appreciated if someone could help resolve this issue!
