I have the following script:
mods.multiblockstages.IEMultiBlockStages.addStage("blastfurnace_basic", "IE:BlastFurnace", "Need Research First");

However I can form the multiblock even I don't have the required stage. Could this be induced by latest change in IE 0.12 - 92?

• Added a second MultiblockFormEvent to the API, to fire after the structure has been checked (BluSunrize)

Shouldn't have broken anything, but I plan to add switch to that event anyone once I get a few minutes (As literally Blu added that event at my request)

I did a test with build 91 and it works fine with that version :)
