Tried placing it in the slot, it will not go in, tried shift clicking it in, will not go in.

Modpack-

Thanks for reporting, though I'll need some more details to track down the cause.

• Is it vanilla gunpowder? (Some Mod may have replaced it for custom behavior)
• What forge version are you using
• What inventory utility mods have you added (InvTweaks etc.)

Cheers!

Vanilla Gunpowder-

Well crud, it doesn't happen with just Create_, Inventory Sorter, Random Patches, and Sulfur and Potassium - More gunpowder. so it's one of the other 143 mods.

It is a mod interaction.

We found it- Time travel mod- apparently they have placeable gunpowder-

As far as I can see, they only add a new block type, similar to Redstone wire. They don't change anything for the actual item.
Have you checked whether the presence of the TimeTravelMod is the cause for this behaviour?

One thing is for certain, though- Since I'm not using generic checks for the items, any modded variant of a material won't be accepted. Fixing that has been on the list for a while.

yes, we reproduce it with only Create_ and Time Travel mod.
