@barcicha - That's because it should be leveling up welding skill, which is different from metalworking (blacksmithing) in Build 42. Are you sure it's not leveling up your welding skills instead as should be?

Yes, welding was leveling moment before with welding indicator, after that appears metalworking indicator but nothing was rising anymore (not welding, nor metalworking).

@barcicha - Can you explain more? The broadcast should level up 1 and half levels in Welding. It does not have anything that levels up metalworking in it. Also, broadcasts for Day 7 is news broadcasts (no XP gain) and the day after it is all skill shows. Could that be why you aren't leveling up?

I tested the mod and reached Day 6 and it works as intended and the days after it too.

After watching I have welding 1 and half too. Only the appearance of an indicator of the growth of metalworking was misleading. That's why I thought metalworking should rise. Metalworking indicator shows for sure in the moment of "[The screen returns to James demonstrating a different welding technique. He picks up a MIG welder and explains.]" and probably for sometime before that.

As mentioned, there is nothing that levels up metalworking in that broadcast, so it might be something else triggering that skill improvement like your actions while you were watching or another mod. Idk. I found nothing wrong in the code or related to metalworking (blacksmithing) in that broadcast, only skill level ups for welding as intended.
