This only occures on the multi-block version and not the single block. Works fine otherwise. Tested in SMP and SSP.

ATM8 1.0.10
MEGACells version 2.0.0b7 (forge)
Forge 43.2.3

I have this issue as well. Also ATM 8 1.0.10, with the same Forge and mod versions

The full block version displays the pattern slots properly in two rows, while the panel version displays them as one long row

Sorry for the late response. I believe I've fixed this in the latest commit; turns out I had forgotten to attach the appropriate menu to the part version as well. 😅

I'lll close this issue once a release has been pushed containing that fix. For now, I would like to find the time to get back to development in order to sort out another large feature or two to go with the current beta features.

No patch yet...

I've pushed a build out now which includes this patch. Should hopefully be out within the next 20 minutes.

E: 2.0.0-beta.8 out now, which should have fixed this.
