Issue description:
RFTools Spawner and matter beamers are not transfering "Live Matter" from the matter beamer to the spawner. Both "Key Matter" and "Bulk Matter" work but the Live matter doesn't seem to want to be injected/put into the spawner. And yes, the beamers ARE linked to the spawner and it DOES have a syringe in it (Endermen in this case).

Steps to reproduce: N/A

Versions:

• Minecraft: 1.12.2
• Forge: -
• CompatLayer (only if on Minecraft 1.10 or 1.11): N/A
• McJtyLib: -
• RFTools: 1.12-7.71

Playing on: FTB Revelations Modpack
Using: SpongeForge (FTB Revelations Modpack)

Possibly incompatible mods and versions: N/A

Relevant logs, if any: N/A

There might be a config issue. Try regenerating the rftools configs (i.e. remove them and start pack again)

minecraft 1.12.2
RFTools: 1.12-7.72

Also playing on: FTB Revelations Modpack

Attempted the suggested workaround by @McJty, deleting the rftools config files and restarting the pack. Everything worked perfectly after.

You just go to the config folder of your minecraft instance and delete the files

I have the same issue but i am not really sure how to delete the rftools config files.

Hi im having the same issue trying to spawn the dragon ive deleted all the config in the rftools folder and the problem is still happening and i have no idea how to fix it

@chiman132 1.12? Can you show a screenshot of the living matter you're trying to insert?
