OK, so interestingly FcmOption is really small, so that is a good start for a reproducer.

FcmOption has 3 @Child annotations, one for each class extending FcmOption. It seems when compiling the module after a clean, somehow references to FcmJsonSupport.scala are added to those @Child annotations in the tasty file for FcmOption (but it seems nondeterministic to which of the @Child annotations they're attached). When compiling FcmOption.scala in isolation, however (even from sbt), those references are not added at all.

(looks like this missed the train for 3.3.4 but will likely be backported to LTS in 3.3.5)
