It works for me. What does not work (2 crashes for the same action) since the new stellaris update is the pop transfer (I had 2 crashes while moving pops between my 15 unicomplexe/else).

Pop assimiliation via bombarding works tough, every now and then I see a pop assimilated popup when bombarding a planet...

I have the ST:NH mod + the BORG UI (only).

Invaded El-Aurian and assimilated them that way. Meanwhile adopted assimilation and harvesting traditions.

Now trying to bombard Lyridian Diaspora, same problem. Bombarding (harvest stance, cannot change) just kills all pops, no messages, no change im my population.

Makes Borg unviable and weak.

Is it maybe because they are mechanical/part mechanical population? Maybe non-organic species can"t be assimiliated? As there is no guide, I don"t know all the rules...

I know that I can"t drop Borg troops on a planet that is "uninhabitable for my specie" meaning, a K or J-class planet can't be invaded (all the planet that are not usual for life as we know it), instead of the M-classe planets (and other rock solid ones with atmosphere) etc. that can be invaded (sorry for the approximations, even if I watched all the ST series, I don't remember the exact classificiation.

If there are Borg experts, please answer the OP, I only have 2 runs with the borgs (easy to play imho, when no weird bugs/crashes).

I've been assimilating populations via bombardment with no issue, but I've noticed that I don't seem to be assimilating ships trying to disengage any longer. Still early on so the fleets involved in fighting aren't huge, but I do remember it happening fairly consistently a while back. Did that nifty bonus get removed?
