Some of the research items have numbers next to them that denote research levels, such as Laser Turret Damage or Worker Robot Speed. While browsing the research tree, I noticed some inconsistencies:
1. Electric Energy Accumulators has a "1" on it despite it being the only research with this title (i.e. there are no additional levels of Accumulators to research).
2. Even though Advanced Electronics 2 has a "2" on it, Advanced Electronics does not have a number. This is the same with Automation, all modules, power armor, personal roboport (first level does not have a number, but the rest do).
3. Most equipment for modular/power armor that has a second, upgraded level is called MK2 (e.g. battery MK2 equipment, energy shield MK2 equipment) except the personal roboport, which is just personal roboport 2.
This is definitely the perfectionist in me talking, certainly nothing game-breaking here, but I'm hoping it helps you polish Factorio up a bit. I believe nothing has changed recently and that this issue persisted from 0.15 or even earlier.
Thanks for reading, and I hope you all have a very Merry Christmas (if that's your thing)!
