  1. Base on my experience if you upgrade lab while it researching, the reseach will keep going. There’s a bug when the upgrade finnish, maybe all you need is re open COC and the reseach time back normal again (in my case, I just go do some raid). For example based on my experience: I research lv 5 barbarian which is spent 5 days to upgrade, and I immediately upgrade my lab to lv 7 (th9) which is spent 5 days too. And then when my lab is finish upgrade, it shows my barbarian research still remaining more than 3d. At first I was shocked and feel hopeless, until I decide to do some raid and back to my base. Guess what? my lv 5 barbarian research is done. I think it’s glitch. But trust me, all of my clan mate do research while upgrade their lab. and the research still on going.

  2. Here’s my result for wasting time:

    Total duration research
    Elix troops = 301 days 6 hours
    Elix speels = 107 days
    Dark troops = 204 days
    Dark speels = 78 days

    TOTAL = 690 days and 6 hours

    2 years = 730 days – 1 month (30 days) = 700 days

    So, if you nonstop research your lab, it will need 1 years, 10 month, 20 days and 6 hours.

    Am I doing it right? CMIIW

    I’m too lazy to calculating the cost, because for me searching loot for upgrade isn’t that hard.
