Hello
From version 1.1.5 to 1.1.6 or 1.1.7 you have removed about 70 lines in the file accumulators.lua which made it impossible to build the following things in the game accumulator level 2 and 3 in all variants

I can't reproduce this. It works fine for me. Is it just in an existing game that you're having the issue? Does it look correct in a brand new game? If so, it could be a migration issue 🤔

Hello,

i think i got the same issue, even when loading a new game in sandbox and cheating all technologies there are no options to get accumulators other than the vanilla one. There is also no research available for that. Solar panels work as expected.

Maybe some incompatibility with another mod? Can someone help me to reproduce the issue?

Open mod settings. Under Bob's Power, there will be a setting to enable higher tier accumulators.
