I'm glad you figured it out! If it comes up again, I'll come back to your comment and add it to the mod description haha

Thanks for replying OP.

I figured it out. PSA for future Steam deck users, use Proton-GE for the compatibility layer.

This mod is still running good. Might be worth checking your logs.

I'm not sure if there would be specific compatibility issues that might come up when using a Steam deck, though

Does not work as of this time? Playing on Steam deck

You're welcome! I'm glad you like the approach I went with. :D

Thank you! I appreciate the tidiness of this one compared to a similar mod I've seen.

Great :D time to tinker a little bit xD

Added a config file :)

Yay, well done and keep it up =)

Thank you! Yeah, I could add a way to configure what's displayed. I'll do that in a future revision.

As for your issue, it appears to be a bug in the base game (unmodded, as I tested without mods as well). In simple terms, the game uses a function to get the price. That function doesn't see all the equipment mods right away; but when that function runs, it brings those equipment mods into view. After that, the next time the game calls that function to get the price, it sees them and evaluates those too.

Thankfully, because of this strange behaviour and the way my mod is coded, my mod should always reflect the final value.

Well, looks like its not the mod, as that happens without it too. No idea why the price is changing tho.
No skill involved has had a level up recently (base/char).

Looks very basic and clean. I like that.
Can you add options to further show/hide values (or a simple config file)?

Yet I noticed some odd behavior for weapons with mods installed. The mod seems to recalculate the price and sets it accordingly, unlike the base game.

Is this intentional?

Thank you! Just a side note, this is currently working on the nightly build as well which is what I'm playing. I think maybe in the future; tying this to appraise/merchant's guild or something might be the best way to make it feel more authentic and part of the base game. But regardless, this genuinely felt like a must have in this game for me, so here we are. :P

Value is very accurate, a must have mod!
