Islandwalk causing creatures to be unblockable without islands

[Davrial]

Describe the bug
Merfolk Soldiers' Streambed Aqutitects applying +1/+1 and Islandwalk is causing the targeted creature to become unblockable even if no islands exist on defending side

I believe this might be an issue related to its other ability, which makes a targeted land into an Island. But it's not using that ability as the two are mutually exclusive by each requiring tapping.

SIGNIFICANT UPDATE: It just caused multiple enemies to become unblockable. In addition, there was a merfolk being swung at me who natively had Islandwalk, and it was actually the only one i was being allowed to target to block

To Reproduce
Steps to reproduce the behavior:
Fight a Merfolk Soldier without any blue cards

Expected behavior
Istlandwalk, as described on the card text, is only supposed to make a creature unblockable if the defending player has an island. Instead, this affect is making them unblockable entirely. Im not sure if this applies to other Islandwalk cards or not, as ive been killing or removing them before it'd be evident.

Screenshots

Streambed Aquitects (far left creature on opponent side) targeted Merfolk Wayfinder with it's first ability, the +1/+1 and Islandwalk
Merfolk Wayfinder then attacked
I was unable to block it with my defending Drowsing Tyrannodon

I think having Islandwalk might be bugged overall. That or maybe blocking as a whole.

I just summoned this dog to block the merfolk i have highlighted. But i cant, as you can see it's zooming in instead of declaring a block

@Davrial check if your cardscripts are not outdated

we recently updated Islandwalk into a more generic Landwalk:Island

• you obviously can't block a flying creature with non-flying Dinosaur
• you can't flash in an additional blocker during Declare Blockers step, that's not how the rules work...

Ah yeah that's my bad. I had already encountered the problem twice before and i was irritated enough about it that i didnt realize that this specific creature was indeed flying.
As i mentioned in that update though it ended up applying to multiple creatures too, whom definitely didnt have flying, as they were random tokens.
Unfortunately i did not get a screenshot of that as i didnt think i'd die from it but i mismathed and died.
If i encounter any more merfolk i'll take a picture of a proper instance, unfortunately i compelted the related quest so idk how long until then it'll be
