After applying patch 1.0.18, the following issue occurs with the State Link “Touching Tile”:
Since reverting to the previous version restores the original behavior, we believe this is a bug introduced in patch 1.0.18.
It also happens to me in all the projects that have a falling action when the ground is not touched after applying the patch. You try to walk and start reproducing the falling animation, and then the waiting animation, as if for a moment it does not detect the ground collision when you are about to fence at the edge of the tile. I don’t know how they didn’t give this much unless they do the tests with projects that do not use that condition, which I don’t see as logical in an engine where one of its main uses is for side platform games. 
After trying various approaches, I suspect the bug mentioned above is caused by a separate issue I’ve posted about: “After applying the 1.0.18 patch, the AnimationPlayer ignores the configured keyframes, causing the wall collision size or position to change unexpectedly.”
Since the wall collision is being overwritten unexpectedly, I believe state transitions via state links are becoming unstable.
A specific, minimal reproducible project is needed to aid the discussion.
Thank you for your message. Can I send you the project for your review?
The forum’s posting system allows you to directly upload an attachment. Could you create the simplest project that can reproduce the issue?
After testing, this issue can be confirmed in version 1.0.18. The bug has been reported.
Thank you for your bug report.
We will continue development on the previous version until it is improved.
