It only happens on the compact machine containing Botania, the report seems to suggest something to do with the mana pool.
So basically I have had this occur a number of times, now its accidentally right clicking as I've stopped using the function intentionally. It occurs every time and only on the one machine, I have 7. The crash report is ************
The game crashed whilst ticking block entity

Error: java.lang.IllegalArgumentException: Cannot get property PropertyEnum{name=variant, clazz=class vazkii.botania.api.state.enums.PoolVariant, values=[DEFAULT, CREATIVE, DILUTED, FABULOUS]} as it does not exist in BlockStateContainer{block=minecraft:stone, properties=[variant]}

Playing DW20 modpack v1.4
Compact Machines v 1.12.2-3.0.3-b169 (btw just started the game to take the screenshot and accidentally clicked and crashed)
Forge v 14.23.1.2566
There's a vanilla forge?
No Optifine

Maximum Machine & 9 mana pools, generation by 10 or so endoflames
I don't know if the image is added by dropping, trying selecting sorry if you get 2 copies
When you tested did you have mana in the mana pools?

Thanks for looking at this and thanks for the mod, I am enjoying it. Also wondering what will happen when I put my 10 compact machines inside an ELEVENTH compact machine?

Could you try upgrading the mod to the latest version? I've changed quite a bit regarding the machine view.

That fixed it, thank you

Hey, thanks for the report.
You can disable the TileEntity rendering clientside in your compact machines 3 config until I've fixed this, so you won't crash anymore.

I can not reproduce this - pools are being rendered, spreaders are not, but no crashes at all:

Please read this and provide me screenshots of your setup, i.e. at least the inside of the compact machine that's crashing you.

You are welcome!
