Hi! data.lua:130 sets quality_affects = { health = true, range = true, attack_parameters = { damage_modifier = true } }, but turrets have no such property in 2.1 and the game ignores it, so this table has no effect. (icon_mipmaps at :112 and :150 is ignored too.)

Do you have any suggestions? I'm currently busy with my university studies and don't have much time to work on fixes right now.

Sure! In data.lua just delete:

• newEntity.icon_mipmaps = 4 (line 112)
• the newEntity.quality_affects = { ... } block (lines 130-134)
• icon_mipmaps = 4 in the item (line 150)

Health and range already scale with quality in 2.1 without any extra field (legendary MK1 has 5000 health instead of 2000, and turret range uses the quality's range_multiplier, x1.5 at legendary). Turret quality can't scale damage in 2.1, so that part of the table has no replacement.

If you put the source on GitHub, I can send fixes as pull requests next time, so you only need to review and merge.

Thank you very much for your suggestions! I plan to make the corresponding fixes this weekend, and I will also update all the mods in this series. Thanks a lot for supporting my mod!
