Issue description

A occurs when Ender IO Redstone Conduits are placed adjacent to Botania's Mana Pool (or when the conduit network ticks near a non-Mana-Pool block). The root cause is that forcibly casts the block entity to without prior type checking, leading to a crash when the block entity is actually from another mod (e.g., Ender IO's ).java.lang.ClassCastExceptionManaPoolBlock.getAnalogOutputSignal()ManaPoolBlockEntityConduitBundleBlockEntity

EnderIO has fixed this issue. This issue is closed

I'd say this is mostly on EnderIO to fix. They should not be applying block logic to places that don't have that block type.

Same issue on 1.20.1, apparently: Team-EnderIO/EnderIO#1085
