Elemental Cannon and Arrow towers lose upgrades after saving game

It seems that any cannon and arrow towers that have been given an elemental upgrade will lose their upgrades upon loading a saved game, and the gold spent to upgrade them is not refunded. I've tested it several times.

For the record, I'm running the latest paid version on a galaxy s7 with the latest Android OS

Interesting. I will take a look.
