Could it be this commit from 17 days ago? https://github.com/magefree/mage/commit/a307e5934f850b8936774a95787d4978d69ee179#diff-75a9ccc52ad403d9ef99f585c3bc56e1e913cb5730cfb77a7ae0feafea21c8e1

@sprangg that code added full filter checking. So if some card's filter is wrong then that card can be broken now (example: it it have a controller/source predicate -- it ignores in prev versions but apply in current).

I need card example and what's wrong description for research.

Ok results so far: When there are no swamps on the battlefield swampwalkers can be blocked, but when either me or the opponent has a swamp, they cannot be blocked.

I tested with a deck full of different swampwalkers, and so far these all have worked in the same way described above:
Street Wraith
Bog Wraith
Quag Vampires
Zodiac Rat
Whispering Shade
Filth (just tested as a creature on the battlefield, not in graveyard)
Zodiac Snake
Witch Engine
Plague Beetle

This should be enough of a sample size of cards? I'll test other landwalks next.

Did a quick test with mountainwalk and forestwalk. Both work consistently with the above swampwalk test: if I have the mountain/forest on the battlefield, the opponent can't block any of my landwalking creatures.

The forestwalk test deck had snow-covered forests and Rime Dryad (snow-covered forestwalker) was also unblockable.

It didn't matter whether the creature gained the landwalk through an ability - they were still unblockable. Tested this with Enslaved Scout and Elvish Pathcutter. If I gave them the landwalk they were unblockable like other landwalkers, and if I didn't give them the landwalk the AI blocked them normally.

Mountainwalkers tested:
Canyon Wildcat
Enslaved Scout
Goblin Scouts (creates 1/1 mountainwalk tokens, worked similarly as nontokens)

Forestwalkers tested:
Unseen Walker
Mirri, Cat Warrior
Elite Cat Warrior
Vine Dryad
Somberwald Dryad
Zodiac Tiger
Heartwood Treefolk
Zendikar Farguide
Leaf Dancer
Zodiac Monkey
Emerald Oryx
Rushwood Dryad
Scarwood Bandits
Willow Dryad
Lynx
Shanodin Dryads
Cat Warriors
Zodiac Rabbit
Elvish Pathcutter
Jukai Messenger
Rime Dryad

Looks like this was fixed by https://github.com/magefree/mage/commit/5f80dba107f566bce801b7b5e81de6b44945fbca
