I just want to get other peoples thoughts on the free speed up (under 5mins build times). I think it's great however the game only allows you that benefit if your current building project would have been under 5mins with construction level of '0' (i.e. I can build a level 3 iron mine in 2.5mins yet I don’t get the free upgrade). If feel that this is unfair for those who have spent the money (which is a lot) and time (194 hours from lvl 9 to 10) and I feel the game should check current build times regardless of construction level and award the free upgrade if your build time is truly 5mins or less. (Does that make sense?) Thanks!
