First batch.

Cursor Decals do not draw when hovering cursor over Radar in Thyme. Tested against Original. To reproduce, select a ready China Nuke Missile attack, and hover the mouse over the camera position on the Radar. The decal will not be drawn on Terrain.

Decal should draw on Terrain like this when hovering mouse on Radar

Special Powers Cursor decals work
Object changing team looks normal (USA05)
Ghost build object works
Unit interaction through window works normal
Various mouse cursors work

Superweapon timer list issue fixed.
