Yeah I don't think an update is usually required for this kind of mod. It should still work as you said since it only has stat changes. I just pulled it up and the health points seem to be altered still just at lower totals. Still a change just not as listed on the modpage will need to update that. The other stats are as they should be though, and I think he is still bigger. So, other that this mod still works as intended.

Is an update required? I assume not as it simply changes stats, meaning that it shouldn't be effected by content and mechanic updates?

since Kholek is my favourite LL, I salute you for this ;)
