Blackrock Foundry Blast Furnace encounter bug?

In 8.2.5 the encounter only needed 3 bombs per heat regulator today suddenly it need about 18. Is a bug or intended?

I have also been having this issue starting with this weeks reset. I did a full BRF clear with no problems on Monday, but now they seem to be needing the pre nerf number of bombs.

nerf plz

12+ characters farm its a pain at this…

This is still bugged, unless the nerf was an unintentional bug and wasn’t supposed to speed up the run, but I haven’t seen any confirmation about it anywhere.
