Minecolonies version version 0.6.2290 Expected behavior - when I upgrade some buildings such as the Town Hall level 2 or the builder's hut at level 2 everything should proceed without problems Actual behaviour - when I upgrade some buildings such as the Town Hall level 2 or the builder's hut to level 2 the builder asks me to give "0 Air Block" which is impossible, and prevents me from continuing the construction. Steps to reproduce the problem 1. build town hall lv1 2. upgrade town hall to lv2 3. builder will ask for "0 air blocks" and stop working [image: 2017-01-31_23 45 29] <https://cloud.githubusercontent.com/assets/25468646/22487859/6b33bc6a-e80f-11e6-83c7-a211698d8348.png> — You are receiving this because you are subscribed to this thread.
