Problem Description

this error spam my console everytime (ps: don't look fr.yanisssch.PWP.* it's just perworldplugin)

Did you have this issue with previous version of OCM too (eg 1.7.2, 1.7.1)?

i think from 1.7.1 but i'm not sure because i can't test everytime i don't have a lot of player on my server x)

Caused due to an oversight with 1.9 compatibility, since 1.9 has no magma blocks and therefore no HOT_BLOCK damage cause (courtesy of the server log from #313, thank you). Fixed in b8697b3.

Please use dev build 52. I tested and the problem was fully resolved on Spigot 1.9.4 for me, so I will close the issue for now. Please re-open the issue if the problem returns.
