On my server, MC Version 1.12.2, Forge Version 14.23.5.2768, I encounter an odd crash when trying to enter or come near a vehicle
with the error:
at com.mrcrayfish.vehicle.client.HeldVehicleEvents.patchPlayerRender(HeldVehicleEvents.java:46)
at com.mrcrayfish.vehicle.client.HeldVehicleEvents.onRenderPlayer(HeldVehicleEvents.java:38)
at net.minecraftforge.fml.common.eventhandler.ASMEventHandler_1359_HeldVehicleEvents_onRenderPlayer_Pre.invoke(.dynamic)
at net.minecraftforge.fml.common.eventhandler.ASMEventHandler.invoke(ASMEventHandler.java:90)

at net.minecraft.client.renderer.entity.RenderPlayer.func_76986_a(RenderPlayer.java:28)

Now I figured it out the first time that BiblioCraft's Armor stand led to the error so I disabled that block and it worked.
The second time it said Galacticraft, but no block to go off of or ID, so here I am.
In fact, all the vehicles crash upon entering now that I updated your mod to the latest version.
Any idea? Maybe I need to change some sort of Entity ID on one or the other because they're using the same entity or ID? Help would be appreciated because I'm stumped.

EDIT: It's on the 0.44.1 version that causes this issue. I went back one version to 0.44.0 and everything works as it should...

Update to the absolute latest version of Forge for 1.12.2
