Around 10 mins ago, in a battle against Mom, I saw Mom's block roll for Parry reduced by a couple of points when I used Puncturing Stab. Puncturing Stab doesn't have any 'hard-to-block' effect, and the enemy didn't have any cards attached to them - so this looks like a bug to me. This happened immediately after I played Tricky Stab on the same enemy. I suspect that's somehow related. Here's a section from the log of the battle. (But I can't see it mention what the block rolls were or anything like that, so I guess the log can't directly confirm what I think I saw...)
Hello, I saw this bug lot of time, but I didn't saw why this bug is here. For me, this bug was always with the elf warrior. Friendly, Platouf.
Ah! I think Cuddlepie has Massive Chop in hand. We should probably reveal that card when it triggers.
I looked up the battle details, and yes, Cuddlepie did happen to draw Massive Chop at the start of that round.
