Playing Star Technology, ETA 3 Hotfix 2 with some extra additions

[yuuki1293]

Please provide a screenshot of your setup.

[WhitePhant0m]

I think it happened with this one?

Pattern providers pointing at interfaces on a subnet for the machine

[WhitePhant0m]

Or it might've been with the multi pattern p2p setup I had earlier, which didn't seem to work at all? One of the two.
p2ps on pattern providers are set as inputs, while one pointing at interface is set to output

[yuuki1293]

v1.2.6 might have fixed this. Even if not, it should now output more useful error messages.

[Quest79]

Unfortunately still happening in 1.2.6, same modpack version as the above. I feel like it doesnt like being pointed into a interface and re-routed but thats only a wild guess.

[yuuki1293]

@Quest79 Thanks for the additional information.
To help reproduce this, could you share a screenshot of the setup?
If possible, a copy of the world save where this happens would also be very helpful.

Fixed a bug in v1.2.7 where a storage bus attached to non-GregTech machines would randomly fail.
