You epically failed at youtube tags Don't worry, I did the same thing my first time using them.
Explanation of youtube tags:
Now, the issue is simple: Animations are attached to specific tiles in the tile set. I'm going to guess you didn't expect that? You probably thought they were attached to the blocks. When you redrew your tiles, you probably just randomly inserted them. Tiles with animations attached need to be replaced by new versions. Meaning, when you insert new water, you need put the new water tiles over the old water tiles. The only animations attached to the actual block data are doors.
