"TH ignores the package flags".
My current guess is that stale .hi files refer to another version of a
package, so despite what the -package flags say we pull in two versions of
a package when TH runs.
That said, this should only happen if there are multiple versions of a
package in the package graph. So perhaps this doesn't explain what gwern
reported.
