Additional comments:

Let me guess: this happened within seconds after the previous upgrade finished?
I had a similar prob months ago. There is a thread about it somewhere...

Yes, it happened after the upgrade was supposed to be finished. I dont know exactly how long it was since it finished, but it was within 1 hour(because I checked before the race in my league).

Come on, guys... I almost finish the upgrade again, hopefully this time it will also upgrade the building...

Hey there, I'm sorry to hear you had this issue, your Technology building should be level 9 now.

Please note that before upgrading the Technology building again, you may want to consider purchasing the Boost and DRS technologies first.

Thank you for your help, Yunus. It’s ok bow, the Boost Building is level 9. Good luck with the other bugs ?
