Mod Version: 3.2.13

Issue: Take a rat (on your person) across a portal and it doesn't make it through. It's not present in the overworld when I get back either.

Steps:

1. Make a rat (in my case, it was a nonbeliever, flight, damage protection, asbesto rat, voodoo)
2. Shift+Right click it to get it onto your head
3. Go through the portal to ratlantis
   The rat is missing when you get there. It's missing even when you get back. Shift+Clicking, using the flute, using the sack with net, none of them report that the rat's around anymore. Given the upgrades I used on this rat, this was a very expensive bug :).
