Since 19.2.0, each time i reroll a riven mod the cycle counter goes up by 2 instead of 1.
Exemple: Riven is at cycle 0, i reroll for 900. Riven is now cycle 2. Next reroll will of course cost 1200. This effectively doubles my Kuva costs increase :O
Didn't notice it the first few rerolls. Then was not sure, so had to check, and double check... won't do it again for screenshots unless requested since it has already cost me thousands of kuva and substantially lowered the value of my mods
