Placed an NBT Extractor and a Variable Store next to it -> Instant crash
Tried after updating Cyclops Core, Common Capabilities and Integrated Dynamics to newest versions and it worked. So its obviously a problem with outdated versions.

I'd suggest to specify a minimum version somewhere (don't know if thats done in Curse or the Mod?), so people don't get confused with it.

Crashlog

Hello again. I am not able to access your crashlog. Can you re-upload it? I think if I can see what is causing the issue, I can avoid having to manually test all versions to determine the minimal requirements.

I was able to reproduce the issue myself. I picked a random version of Integrated Dynamics afterwards, which is v1.1.2, and it worked. So I am going to use that as the minimal requirements.

Anyways, thanks for letting me know. :)
