When I go to the shop in Act 1 of Hallownest mod and Ascension 20, this error occurs.

https://pastebin.com/bAi43hnz

Thanks for the report, that happened because one of the cards in the shop ignored base game keyword conventions, something I didn't account for.

The update should fix this but it may look a little strange on whatever card that was.

The only problem I've noticed is that forcibly adding extra relics to the shop makes it possible to obtain two of the same relic due to the way seeds work. It might not even be fixable, but most if not all relics don't stack.

That is quite baffling since I actually trick the game into using the base method to expand the selection. (this means the seed-counter is advanced properly and thus not the issue)

The only way that could happen would be if a relic was in the pool twice which would be a problem another mod would be causing.

Hmm... Not a clue. It could be Ruina I suppose. It wasn't a modded relic that I got twice, but maybe adding entirely new acts and thus map layouts can also override your change and alter which relics are in chests etc.? I might have to test it more.

I am unsure if it is intended this truly a bug, it may be intended this way, however items added by the Courier relic are unable to have modifiers.

Thanks for the report Avangion, hopefully fixed.
I'm aware of it but I didn't think it was necessary, it would allow people to farm for powerful combinations under certain conditions.

If i enter the shop In Act 1 of Menagerie mod, it occurs:

Updated with a fix

Could you add compatibly with The Duelist mod? The refund tag doesn't seem to work with it's cards

That sounds like more of a problem of StSLib (the library that gives access to the refund keyword/feature) and even then, it not working is most likely duelist's fault.

Might be worth asking over on that page, not a lot I can do about it in this mod

I got senshi mod and infinite spire
when i turn around to enter the first shop i cant retireve gold even after restarting

more of a minor bug then a major anyone knows why ?

Conflict with Twitch Slays Spire Relics, as I used Dice of Fate and game crash:
