[running 1.12.2] Does anyone know how to create a mob spawner with the dalek mod entities? Using setblock doesn't seem to be working. Neither does right clicking an empty one with a spawn egg. Is it just completely incompatible?

Update:

use /setblock ~ ~0 ~ mob_spawner 0 replace {SpawnData:{id:"thedalekmod:dalek"}}

Note the full 'thedalekmod:dalek' instead of just 'dalek'. And it needs to be encapsulated in quotes as to not be confused with the second ':'.
