GMS Unleashed - bugs and problems

1) What level are you? If you're too far below the monster's level, you can't see its card.
2) Did it drop anything at all (meso, potions)? If it dropped nothing, you might not have waited enough. It's 30 minutes from when you summoned the body, not 30 minutes overall.

1. Mine is 176.
2. Yea it dropped other stuffs (meso, pot, circ, dragon's egg...) but not a single card, we waited for 30 min since summon. This happenned to all of my party, we couldn't see the Horntail card dropped :-\
We went to HT 2 days ago :-\
