There are errors in the log, but it is only related to the trader and the villager. And why can't loot be shown? Is it not added by the author of the mod or is it some kind of resource problem? In fact, there are a lot of such problems with not showing a drop. I'm just trying to figure out if this is a problem with the mods themselves or if a fix is needed on your side?

At the same time, there may be a correct drop display in the same mod. For example, in "Born in chaos", the screenshot is below.
