Describe the bug
I'm reassembling my modpack for 1.12.2 with Fluidlogged API v2.2.1, and tried to run them on Mohist (hybrid Forge + Spigot server), but unfortunately i got this crash when trying to boot the server.

So i went ahead and opened a ticket on their repo, after an investigation done by @Mgazul (i sent him the whole server folder as a .zip) he determined that it's a problem on Fluidlogged API side, and Mohist can't try to fix solemny on their side.

So i decided to open this ticket here to see what can be done about it.

MohistMC/Mohist@aa40842 Fixed this

Fixed! Thank you so much @Mgazul and sorry for any inconvenience @jbredwards
