That was fast! 
And two more bugs that can be easily reproduced by loading the VCMI_Tests.h3m attached to my post above:
#78 Rampart Town Hall upgrade is missing some huts that should be added to the town screen:

[size=75](I suspect this is similar to #34 reported by pHOMM, indicating various town screen elements not included in some upgrades…)[/size]
#79 If we build upgraded dwellings before the hoard structure, the graphical part of the hoard structure appears together with the upgraded dwelling:
- Upg. Griffin Tower comes with Griffin Bastion
- Upg. Dwarf Cottage comes with Miner’s Guild
- Upg. Dendroid Arches comes with Dendroid Saplings
- …and so on. I haven’t tested them all, but I suspect it’s general.
The other way around we don’t have an issue - building hoard building first does not build upg. dwelling as well.
[size=75](I’m pretty sure this is the cause of the bug reported by majaczek as 0.72#1, which was not kept in the logs - I guess because it was not clear how to reproduce it)[/size]
