Patched a whole lot of bugs

Devlog #7 for “Boom” protector
Since last time’s release a completely insane and game breaking bugs, thus I spent this time patching as much of them as I could.
The main two most important bugs I patched were:

1. New tower spots would never disappear and you could click on the spots, which would decrease your balance while not placing anything down, cause there was a tree already. So now they behave correctly - they no longer show up when they shouldn’t.
2. Null’s speech problem - In the last version if you clicked before null finished speaking, he would start speaking in a language unknown even to us developers. Now he just speaks normally.
