@Korzeam, I found a bug in the Living Blood skill on the Death Knight. When we use the skill and we do respect skills, but the skill still works even though the skill points we have given are gone.
If I'm not mistaken, maybe you can give an "Event end" for that skill. So when the skill is respec, the skill will stop working, but I am not sure.

Speaking of bugs, I read the comments on Steam there was a bug when doing respec. I have tried the latest version in steam the problem I found was only in the Living Blood skill when doing respec the skill still worked, but I didn't find any other problems with the skill that gave the skill point when doing respec.
I did respec skill testing with:- Only use Deathknight Mod
- Using Deathknight + Synergies Mod
- Using Deathknight + Ultimate respec lite Mod
For respec stat I also didn't find a problem when using with Ultimate respec lite Mod.
I did respec stat testing with:- Using Deathknight + Synergies Mod (Can't do stat respec)
- Using Deathknight + Ultimate respec lite Mod (You can do stat respec)
Even if you play using Deathknight + Ultimate respec lite + Synergies Mod , with the condition to put Ultimate respect lite above then you can stat respect.
I myself use the mod as follows:- Testmerge (in which there is Ultimate respec lite inside it) "Only for personal use"
- Variant Pet
- Variant Class
- FEP +
- TL1CP
- Deathknight
- Classless
- Torchlight 2 Essential
- Synergies
