Open Tinker's Construct Bolts Nerfed?

Is it repeatable? First: Craft a tool rod from blue slime crystal , then a slime fetching from blue slime crystal as well. Pour Enderium on the slime rod. Combine in tool forge to make bolts.
Second: repeat this process after updating to 2.6.0 and you will notice the original's stats' have been grandfathered in, but the new ones will be significantly weaker.

I found this from 2.6.0 changelog

ExtraTiC (1.4.5 -> 1.4.6)
  • Adds Immersive Engineering support - Constantan
  • Fixes Ore Dictionary registration.
  • Fixes crafting of Thermal Foundation's Lumium.
  • Balances Thermal Foundation Materials. [ Personal note: new Constantan is kind of broken for balancing this :^) ]
  • Other bugfixes.
So yes, they got nerfed.


Is there any way to find out how these new re balanced materials will modify the bolts now?
