[Mod Interaction] Modern Skyblock 2 crash pulling smart combustion controller

[BrianEdmonds]

I'm playing Modern Skyblock 2 on a private server, and just this morning progressed far enough to deploy a smart combustion controller. Silly me I misread the instructions and put it on the top, under the sticky piston I use to open and close the chamber. I went to take it apart, and hit the switch to retract the piston to pull the top up so I could hop in to grab it if fell in. The server immediately crashed. The server restarted fine, and after logging in the controller block had vanished.

Looks like a null pointer exception in Sky Resources:

a similar crash just happened in msb3, but not with Sky Resources only. sounds like a mod interaction issue

Looks to my like the tile was destroyed prior to the block. As for how that happened I'm not sure.
