[Question] How set hot keys

[[Question] How set hot keys]

After I bought the custom pass, my hot key is messed up, for example: now there are no hot keys to build Nature and Earth tower. Other hot key to build other elemental tower are also swapped.

So how to rebind the keys like before I bought the custom pass. Thanks.

[Build tower, gold decreased but no tower appears]

As the titled mentioned, I try to build a tower, the gold decreased but no tower appears.

This is not just a graphic bug. Because when the creeps pass through the area of that tower, nothing hit them at all.

I notice this bug after I bought the custom pass.
