Upgrades not showing when you click on them.

[Hivesy-Deluxe]

This has been going on forever but ive only just got round to posting this. Its really annoying when items dont show the upgrade image when you want to upgrade them, if im going to spend money or resources i want to see what im going to get

currently it seems to be all traps, SAM, barbed wire, ambush trap and mines, also caravans. If you go to upgrade them it just shows you the level 1 image.

annoying little bug, please fix this.
