[Oxyd] [0.17.15] Tech upgrade = true seems being ignored

[Schallfalke]

Seems like most (if not all) upgradable or number-suffixed tech have all tech level shown up even if they are all researched.
For example, "laser turret shooting speed 3" and "laser turret shooting speed 4" are displayed together.

In former version (say 0.16.51 - 0.17.4), these tech which has property "upgrade = true" will have the lower levels hidden.
I have not looked into this during versions between 0.17.5 - 0.17.14. But I am sure 0.17.4 still has the researched lower levels hidden properly.

Happen to both vanilla and modded tech.
Happen in both no mods and have mods, by loading save game.

Could you post the save that reproduces this? When I research Laser Turret Shooting Speed 3, I can only see Laser Turret Shooting Speed 4 in the technology list.

Actually even starting a new game (using mods like Creative Mod or Schall Starting Tech to have all tech researched) has the same problem.

I cannot upload my old save game file (17.9 MB), the "STATUS" shows a yellow triangle with "!" icon.
Here I upload a newly-started save game instead. (Which have the same problem.)

Ahh, thanks. The problem only appears when you research all the levels for a given technology, that's what I was missing.

Fixed in 0.17.17.

Nice to see 0.17.17.
But it seems not really solved.

Even all levels are researched, low level techs are still all on the list.

Military 3 not hidden, when Military 4 is researched

Neither military 3 nor logistics 2 are marked as upgrades, so I think this is working correctly.

OK, you are right.
But what about mining productivity tech? I have level 20, but the level 3 still appears in the "green". Looks weird it still show up. (I GUESS it does not show up in earlier version, though I do not have lower version game to confirm this.)
