Bug: Lini's Beast Trick work on Large Chest reward

[Ripe]

In my last game Lini encountered Large Chest and after I used Thieves tools to defeat the barrier.

 

When I was about to roll for reward (d4 random weapons) I noticed that Beast Trick "button" was highlighted so I pressed it and as a result I got to roll 2d4+1 to see how many weapons I'll get (I got 8 total).

 

Large Chest is the only such barrier I encountered so I don't know if it would also work on other barriers (I know it doesn't work on Cure result).

I read in some other topic that this (bug?) can work with the barrier Mystic Inscription too, and it probably works with other barriers with the Cache trait.
