Was making Electrum and noticed that only MI version was seen in REI. Tried to use the alloy smelter from TR and boom - it works. Though the version it makes is not shown in REI. Here`s the screenshot:

The pack version is a bit old - 1.1.4. Havent tested it on 1.1.5 yet. Alloy unification problem?

Fixed it via a conversation in Discord. The reason for script failure - Space Dimensions that was added separately, the mod messed up with the line 90 of the script. Deleting the mod solved the issue and allowed the script to function properly. Will have to modify quite a few AE recipes too)
