Expected result

The costs of building objects and moving the headquarters are included in the "Construction" or "Other" sections, which do not affect the company's operating profit.

Actual result

The cost of building objects and relocating the company's seat are included in the property maintenance costs. In this way, the construction of objects and the transfer of HQ affect the company's operating profit. This impact can be very large when the objects are expensive or company value is high (HQ transfer cost is 1%). This often results in a strange drop in income for players visible on the graph, which actually did not happen.

The situation from one of the online games

Steps to reproduce

1. Run any save, the longer the game, the better (attached one of the online game saves with very long gameplay, use company 8)
   WARP Technologies S.A., 12503-10-25.zip

2. Move the company HQ

3. Change your mind and move HQ again (for better effect;)

4. Look at the operating profit graph - in the case of a long game, you will only see the loss in one quarter in which you transferred your HQ

5. For the next 6 years of the game, the profit graph will be disturbed

6. The construction of objects can also greatly disturb the graph, but here the younger the game and the more expensive the objects, the clearer the effect.
