Effect removal on upgrade

[jolin012]

There was a change, that effects on towers should be removed on tower, to avoid the old mushroom abuse. Nowadays that abuse is no longer possible, while the effect only lasts 3 sec now. Therefore I would like this to be changed back the way it was, and when upgrading something the effect is removed adn that's not a good thing imo, especially not when preparing a defense, manually casting fire up and so on low lvl towers, and when upgrading 'em the effects are removed..

i wouldn't mind that much either way, but he has a good point there.
