Hello
I broke your mode again heh
Didn't do anything special, have no idea why it broke

Crash report: https://pastebin.com/tzWGxzBZ

Now I can't join my server although I updated mod both on client and server.

[18:50:40 INFO]: Attempting connection with missing mods [kimagine, ae2fc, fc-dummy] at CLIENT
[18:50:40 INFO]: Rejecting connection CLIENT: [FMLMod:ae2fc{g0bc3e5b}]
[18:50:40 INFO]: Sacrilegum lost connection: Mod rejections [FMLMod:ae2fc{g0bc3e5b}]

Tried to downgrade client mod to previous version, didn't work.
Server didn't complain about "kimagine" and "fc-dummy" before update, I don't have a clue what is it.

wait, do you update the ae2fc both at server and client side? also make sure the server config file is the same as the client one

does it only crash on server?

Oooopsie forgot to unzip mod on client :(
Should check it before writing you, I'm sorry about this. .zip and .jar looking the same, didn't noticed

Fix works, it seems server don't crash anymore. Thanks for that

do you connect it with enderio conduits or something like that?

Yes I do, both item and ender fluid conduits. They are connected to ingredient buffer. To dual interface connected only item one.

It worked perfectly until I inserted pattern for iron, which was very similar to copper pattern. Iron was ordered by export bus, server died after this.

ae2fc-1.7.10-g0bc3e5b.zip
try this, it should fix the these wired crash from eio pipes
