Than suffer with the errors until the next update supports 1.9 or ask
@jedk1 or someone alike that can make it compatible.
It's more serious than you think, except all those plugins i am using, I had to change many plugins's default sounds to 1.9 sounds but that's nothing, my survival world uses custom biomes, and they how they are right now they are regenerated for 1.9 and they are completely incompatible with 1.8 (It's a plugin that makes the biomes lighter and uses). I have already reset the world for my players and I can't do that to them and destroy their buildings, I've already did 2 resets in total, I don't want to make more for just this, but anyway it's not causing lag and everything works right in bending except sounds, so I can wait
Also guys I never asked for a 1.9 build from anyone, just asking what are you planning to do and I already took my answer, thanks and lock the thread please!
