building_reader_t cannot read standard makeobj version 9 objects correctly.

[Ranran(retired)]

building_reader_t cannot read standard's object (version 9 objects) correctly. (pak.nippon v0.6.0)
Those objects will not generate cities correctly due to corrupted data.

EDIT:
The level doesn't load correctly and the standard object is undervalued by 1.
The presence of level=0 buildings completely breaks city generation.
Not sure if this started recently or has been happening for a long time.

EDIT2:

Code Select Expand

case building_desc_t::city_res: won += h->get_level() * 10; break;
If the building level is 0, the city is treated as not growing even though buildings have been added.
The increasing won/arb is 0 because it is a multiple of level (zero).
 Therefore, keep building level 0 buildings repeatedly.
