CreativeMode Player Flag Prevents Building Upgrades (Plugin Conflict)

Hello,
I am experiencing an issue with your plugin that seems to be caused by a conflict with another plugin.

That other plugin explicitly sets the following flag on the player:

player.SetPlayerFlag(BasePlayer.PlayerFlags.CreativeMode, true);

The issue occurs as follows:
When I use the building plan and try to upgrade building parts, the upgrade does not actually happen. You can hear the sound of the selected material, but the building piece remains at Twig.

It therefore appears that setting the CreativeMode player flag is interfering with or blocking the upgrade behavior.
Could you please look into this and check whether this behavior can be handled or worked around? I would be very grateful.

The developer may have already contacted you regarding this issue.
