Magma key can't open the reward room.

After I got the magma key and threw it on the iron trapdoor, nothing happened.

Which version are you playing on? Perhaps some redstone broke.

[Ironnoob73]

minecraft 1.21.1, mod version 202.

Well this might be a problem caused by another mod, because the item stacking limit of the tripwire hook has been increased, resulting in more tripwire hooks being required to be detected by the comparator 😂
If there is no plan to add another item to replace the tripwire hook, this issue can be closed.

And also, this guy does not seem to have dropped any key...

I'm sorry! I only just saw this bug. How would this happen in normal gameplay? I thought cave air would always be replaced by normal air? Or are you attempting to build a structure with a portal already formed?

Bro you may have replied to the wrong issue. The problem caused by cave air is #93.
