Bug fixes - 05/05/2023

I fixed the following bugs:

Currently the game shouldn't crash upon trying to reach level 4 with a unit.
Level 3 is currently the max level.

Drop and dragging units in the planner can sometimes drop units in a undesired spot.
This is now fixed.

There is a bug where you drop a unit on the shop button it bugs out.
This is now fixed aswell.
