Description: Crash from Rendering Block Entity. This is only crashing the Minecraft client software, not the server. Also, it occurred when I was driving a vehicle (mini bike) from the Vehicle mod.

It happened again. I was climbing up a ladder when it happened. I wasn't right next to a mirror, but a mirror was in the same chunk. Here's the crash report: https://pastebin.com/55mZ39QY

The client crashed. The server didn't crash, but here's the server log message recording my client crash:
08.10 20:38:34 [Disconnect] User fandomaniac has disconnected, reason: Internal Exception: io.netty.channel.unix.Errors$NativeIoException: syscall:read(..) failed: Connection reset by peer

I've seen this, when you place an IndustrialCraft2 block (I used a pump), then place an electric fence around the pump, leaving no gap between them. In Survival, run/ walk into the fence. The game crashes, the crash log has something along the lines of the "Rendering Block Entity", I'll try and post a crash log if needed.
