Nightmare Map change and Nerf to pre-existing maps I lost multiple mirrors from investments

After reading the patch notes like most of the players, I made certain decisions regarding standard items I have brought from league over. I had brought over 6500 Maven's chisels of Avarice with me to standard from Keepers league. I read in the patch that the Mavens chisels of Avarice would only give 50% quality going forward instead of their current 100%.

In the beginning I was planning to just bring the chisels with me to sell because I had purchased them at an average price of 15-20c. After I saw the patch I figured they would be better used If I made maps higher quality first, and then rolled them to higher currency rolls second.

I spent multiple hours rolling 3 quad tabs worth of tier 17 maps that I first had to buy for 40-50c each and spent hours getting the gold for that.

Every single map within my 3 quad tabs were rolled to a currency roll of 240-450% currency. I have now logged in and every single map that I have is set to 20% currency quality instead of the 100% it was.

This has effectively deleted potentially 20-30 mirrors worth of investment that I decided to make. I would understand if the patch somehow lowered their quality to 50% as that was the new maximum but instead they are set to 20%. 20% is not even the current maximum you can get from a new mavens chisel which is 50%.

And why are my pre-existing tier 17 maps being changed for this update why could they just not stay with the same rolls and change to nightmare maps or simply stay as what they were and slot into the new slots that are literally labeled what they are.

I need some real clarification regarding this decision because it would ultimately decide how I play standard from now on and the amount of time I spend playing during the league as well.

To explain this further, Every single map still retains the previous rolls but the quality amount has changed from 100% down to 20%. If you want to nerf me to 50% which I used 4 maven chisels on each (50% only takes 1 now) at least change all of my current maps to 50%. I know this is likely an issue for anyone else who has a stockpile of investment maps on standard and I hope a decision can be made for all players affected in this way. Even if it just means getting a bunch of maven chisels to make them 50% I would accept that.

To add to this, I also read in the patch notes where it said that all Cartographers chisels were going to be unobtainable and currently add 20% quality would only add 10% going forward. I added 20% quality using 4 chisels on each map for over 10 quad tabs of maps. I log in now and can use chisels to add 20% still and it only takes 1 chisel. Going off of your patch notes I have thrown away a few mirrors of future value worth of chisels and wasted many hours of time trying to procure high value items based on the patch notes listed before the update.


If this is not a technical or bug issue I really need to know why things in game are not like the patch described
