Help with bug

[SXScarecrow]

Hello everyone, I am requesting help with this bug. Whenever I disconnect from my modpack server, I get this bug. Is it fixable?

java.lang.NullPointerException

This only happens when I disconnect from the server. It crashes while updating screen events. From what I can see, its an issue with the Voxel Mods I have installed. I don't want to get rid of either of them, can you help me?
