I have found that there are 10 cards in the base set which can not be deselected, at all.
At the end of May of this year, this issue was raised in somewhat similar fashion http://forum.shuffleit.nl/index.php?topic=1853.0
and commented as fixed by Stef:
ok I found a bug & fixed it. It wasn't specifically related to the rematching, but it still seems to have been the cause here.Below I will demonstrate familiar-card selections made to the base set and the errors that occur.
If you had max_unfamiliar_cards set to 0, the first card selected could still be any card you owned instead of just cards you were familiar with.
With all cards in the base set selected, and all cards of other sets deselected [expecting 26, seeing 26]
All cards in all sets deselected [expecting 0, seeing 10]
:To see the 10 bugged cards, deselect all cards, logout and log back in to see this:We can prove the error among these 10 cards in other ways...
Example 1 - Base set selected with the last 5 base cards deselected [expecting 21, seeing 24]
...count incorrectly raised by 3 due to bugged cards: Village, Witch, and Workshop. Logout/login and those 3 will be selected again in the familiar cards selection screen.
Example 2 - Base set selected with the left column of 4 base cards deselected [expecting 22, seeing 23]
...count incorrectly raised by 1 due to bugged card: Gardens. Logout/login and that 1 will be selected again in the familiar cards selection screen.
- COMMENTS -Of course, this is not simply a bug regarding the display of familiar cards in the options...
In-game the 10 bugged cards appear en masse constantly, regardless
of my current "Max unfamiliar cards" setting. Deselect some or all of those particular 10, play a game, and there they are! One can tell that they are not actually being deselected like the other cards can be because the "You're allowing #" is not changing appropriately, and logging out/in shows them selected again.
I only play bot games, but the manner in which I create new tables or re-use my existing table makes no difference. I find the issue occurs on new games, and rematches alike. Logging out and back in to try and workaround the bug in any manner has no effect. The issue is seen on Linux and W10, Chrome and Firefox, and over the entire course of the last 6 months with improving browser versions. There is no apparent limit to the amount of the 10 bugged cards which can appear at once in the same kingdom. I had a paid subscription in the past, and this issue existed both at that time and now while I am currently running in the "free mode." I do not recall for sure if the issue existed with cards from other sets when I was on subscription.
Best of luck to developers in chasing down the root-cause of this bug, I would love to see it fixed.
