Alchemy, Stone changing wrong stats?

[swedishpix]

So i was doing some alchemy, trying to improve an items Parry Ratio (Attribute stone of dodging), when it suddenly says :

[Attribute Assimilation] [Lynx Gale Breast Tasset]attribute of HP has been changed to[600 -> 150]

and i thought hm.. thats odd.. but still kept going.. and then it happened again:

[Attribute Assimilation] [Lynx Gale Breast Tasset]attribute of STR has been changed to[3 -> 6]

I'm wondering if there's a fix to this? This happens often too, i only used 3-5 more stones in between before it happened again.
It's frustrating and difficult to try and improve your items and stats, if stats youre not currently working on are wildly changing.

Attribute Assimilation Is part of the alchemy system, it is not a bug. The stones you use have a probability, check the stone Assimilation Probability %, that is the chance of changing another stat.

You can get 0% assimilation stones from monster drops. If you stack stones with assimilation >0% on top of a stack with 0% stones, they all become 0% assimilation stones.

Okay thank you for your reply, now i know!

(also i think i accidentaly posted this same post twice to the forum, sorry)

or you can stack them, split 1 stone from the stack , then tp and the stone is 0%. Then you can just put the huge stack on that stone
