Please answer soon!

Hi, I'm sorry, somehow you managed to get the wrong tile entity paired to a block. As a possible work around you can try disabling the residual heat block in the Railcraft block config.

@4TheGame3 this error isn't due to railcraft it's on the dragonAPI side of things, the crash is dragon api asuming the TE is one of it's own TE's but it's a railcraft TE so it crashes

its a common error, ive found other posts, please fix!

ok thanks. i also posted this error on dragonAPI github.
