pollution is somethink like omg: i start always with 100 every planet
That's normal: pollution from all surface are taken and put outside, so if you produce lots of pollution, you'll quickly get a lot when warping.
The platform itself always start from 1 and increases.
i start lose laser turrets [...] every time you go in bitter planet have to pick up your top floor cause you cant defend.
Then probably your defense is not good enough, do you have walls ?
Do you have gun turrets ? Red or green ammo for turrets ?
Lasers ?
Flamethrowers ?
Drone for repair ?
Biters have increased resistance with this mod to counter a bit the traditional "all laser" "all flamethrower" defense (depends on tier, so not a lot early, but enough to be a pain if you don't have a good defense). These def may still work, but maybe not as effective as usual.
Also, some planets are designed to test your defense, especially the "death world" planets, where lots of biters are.
i think electria room have to be bigger cause you cant add a lot of thinks there (i play warptorio mods and i feet all oil,batteries,plastic etc and nuclear power)
I'd say, you should be able to fit a lot everywhere. Maybe not using Produstia / its beacon to help your production (with productivity modules / speed modules) also doesn't help. I didn't really design Electria to be used for that actually, it can (and I used it for some production in my run as well), but I don't think space is enough for energy AND production there (especially also as you don't have bonus there)
