The error above is a clash with mods.... as for the instant crafting it is sped up by a factor of .7 once you have both items in the forge... if its insta crafting it may be another mod changing something as there are no errors that i know of in the mod itself
I'm still using v2.87 and i'm not using any others mods I also started a new game to test.
in the forge with anvil,crucible and advanced bellows, I can:
I can craft 100 forged steel in 5.34 min
I can craft 100 forged steel in 0.35 min with advanced engineering level 1 (-20% crafting time in forge)
I can craft 100 forged steel in -1.56 min(instant crafting if you get out of the forge ui) with advanced engineering level 1 and equip the nerd glass(-10% crafting time)
I repeat i'm not using any other mods I only used
"war3zuk-alpha-18-aio-Addon-master.zip" and "War3zuk-Alpha-18-Stable-AIO-master.zip".
Try it yourself If having all the forge tools, level 1 advanced engineering and nerd glass do the same for you, if it doesn't do that for you then I don't know why it does that for me.
could the anvil be the problem with no skill and no anvil, crafting an anvil take 9.10 min after I added the anvil it become like 2.05 min that four time faster not 40%
edit:I'm now on v 2.89 and I looked at the item.xml and I see(I know these are not for the same crafting station)(those number are from what the download give me):
HDMotor500cc
<passive_effect name="CraftingTime" operation="perc_add" value="-.300"/> (based on changelog that supposed to give 30% bonus to crafting time)
toolAnvil
<passive_effect name="CraftingTime" operation="perc_add" value="-.777"/> (based on description it supposed to give 40% better crafting time, doesn't that look like 77% instead)(you add to this 30% better crafting time from advanced crafting 1 and nerd glass, that might explain the result I get)
I'm not a modder so those things might not mean what I think but I thought its worth saying
