It took around 3 weeks to "get" the info that it was a simple "balance" change.
I dont remember a single balancing change like this in the history of this game. It targets a single building, is instantly 4.5x the previous upgrade cost, affects multiple resources and affected just that one upgrade level. It just does not make sense from a balance design perspective. A regular balance change would have increased the original building price with/without the upgrade cost change and in terms of other resources it could/would have been distributed to affect multiple levels and possibly resources.
BB_Trafffer mentioning the explorers also makes no sense as in the past explorer related "balancing" has been fine tuning aka nerf the amount of event resources the explorers bring. It's even been said as the reason for in the past years by BB on the German/test server forums.
BB was most likely unable to find a waterproof refund solution due lack of logs or info of upgrades/purchases of current and past years or it would have required too much effort to update all servers and do/run refund scripts before event ends.
The actual fix for the cost would literally have been a change to 2 lines in the file that defines costs.
