and the pig spawners dont seem to work? D:

It looks like this bug reappeared in 1.19.2:

When unpacking a spawner in survival a pig-spawner appears,
but when you unpack the spawner in creative the correct spawner gets placed.

Forge: 1.19.2-43.1.33
PackingTape: 1.19-0.14.0

Thanks for the report. No need to do anything now, but next time it would be best to create a new issue referencing this one by number (writing #number with the id of the issue).

Actually, the issue was that Minecraft has a restriction that doesn't allow placing mob spawners with NBT data, which my mod was enforcing.

I changed things in v0.9, so that whitelisting a TE will ignore this restriction.
Note however, the configuration format has changed, the TE whitelist/blacklist now uses registry names instead of class names.

I'll check. As you may understand, since they are blacklisted by default, testing if spawners work isn't exactly high priority for me. :P
