A bitmap ID's get overwritten sometimes - graphical issue with irrigation

[axx0]

Suddenly the irrigation was replaced with frigates.
The issue disappears with reloading of game.

I guess it's something with overwriting the VCPU memory where bitmap ID's are located.
This will have to wait a little bit until I finish introducing the parameters to all functions, and then I will move bitmap ID table to a managed array.

Is there a way to reproduce this issue?

Thanks for spotting it ;)

I researched an advance just before it happened, but I'm not so sure it's connected. I'll see if it can be reproduced.

I had this happen also. I had played most of the game using DOSBox, the version of the game was 474.04. Then continued with OpenCiv1 Alpha 7.
