Issue from Wired Redstone: Kneelawk/WiredRedstone#32

Well... I think I found the reason of this behaviour and looks like it's not on your mod side...
Kneelawk/WiredRedstone#52
There you can found some of my tests with redstone wires mod and one additional compatablility test with your mod too...

Hi MAG, thanks for digging into this, and apologies about the rather delayed response. I am happy to see that the problem appears to be sorted out. Redstone is for the modders a real nightmare, as it constantly changes and breaks already in vanilla MC, and adding features to that in mods is even more bridle and include a lot of workarounds. C'est la vie ;).
Thanks again for filing the issue; Cheers,-
