Cursor Broken in Version 2.4.2 (1057)

Version 2.4.2 (1057)

I have this text

ABCADASDA
asdadaaef
/H/

And the cursor breaks

Putting the cursor at the start of line 1 and pressing down takes me to the end of line 2. Deleting the last / makes the first line shift

This should be fixed in the upcoming version.
