Help with TRANSFERCARD to random position in deck

[DKpaladinMDL]

Hello,

I have been working on a Hearthstone plugin for playtesting custom cards. I recently made a Lich class that employs the Scheme mechanic from MTG while also having various cards that say "shuffle this card/some other card into your deck." It's very important that deck order remains the same and so the new card must be placed at some random position in the deck rather than just putting it on top of the deck and shuffling it.

To make this work, I tried making a zone called the "Shufflezone" where you put cards you want to shuffle into your deck. Then there's the "shuffle into deck button", which takes the top card of that zone and sends it to a random position in the Deck zone.

It almost works, however, instead of sending it to a random position number from 1 to n+1 where n is the deck size, it sends it to a random position where n is the hand size. Even though it's going off of the hand size for some reason, it still is sending it into the deck correctly. I am currently very confused as to why this is happening, so any help is appreciated. I thought that it might be in some way related to how I am defining the deck gamezone/deckzone, but I'm not sure. Here is my plugininfo.txt (with the shuffle into deck action bolded for convenience):

Seems like a bug.

I tinkered with your plugininfo and it stopped behaving incorrectly when I randomly put cards from my hand into a new shared zone...

[DKpaladinMDL]

Should I post in the bug report section then?

[AuraDragon]

Sure thing.  I don't know how often Trevor updates Lackey but posting in that area has the highest chance of getting it fixed.

I've been really busy with my baby. I'll continue to code more when I have more time.

Omg!    You're a father?  Since when?  And Congratulations!
