❗ Checklist

• I am using the official english version of Slimefun and did not modify the jar.
• I am using an up to date "DEV" (not "RC") version of Slimefun.
• I am aware that issues related to Slimefun addons need to be reported on their bug trackers and not here.
• I searched for similar open issues and could not find an existing bug report on this.

📍 Description

Block Placer still places spawners despite it being configured not to.

📑 Reproduction Steps

1. Add Spawner to Block Placer's unplaceable-blocks config in items.yml
2. Added MOB_SPAWNER as well, for good measure
3. Load up server, get a spawner and put it in the Block Placer
4. Activate the block placer with a button and read console
5. Error log I posted is the result after pressing button

💡 Expected Behavior

The Block Placer shouldn't place the spawner at all, and should only show a black smoke animation

Spawner Item ID is spawner, mob_spawner is the ID for older Minecraft versions.

EDIT: Just re-read the issue you are having. Can you send the full error logs? Also you can re-open this issue. I can't seems to replicate it on my test server with Slimefun only.
