Thanks a lot for finding the condition for this bug!
The problem is this: Moving the scratchpad eventually ends up in
"sizepolicy_free_snap" (seems to have been in-lined in the build I debugged)
#0 sizepolicy (szplcy=0x88f998c, reg=0x88f93e8, rq_geom=0xbfd774cc,

Here the sizepolicy is combined with border modifiers (e.g.
SIZEPOLICY_HORIZ_LEFT) if the scratchpad is at one of the borders.
This results in a sizepolicy without a string representation (szplcy_specs,
sizepolicy.c:311), so when stringpolizy2string is called when the layout is
saved it returns NULL.
The following small patch fixes the issue: (done against ion3plus with latest
patchset)
hunk ./ioncore/sizepolicy.c 363
- return stringintmap_key(szplcy_specs, szplcy, NULL);
+ char* str=stringintmap_key(szplcy_specs, szplcy, NULL);
+ if(str==NULL){
+ /* fall back on policy without modifiers if full name not found */
+ str=stringintmap_key(szplcy_specs, szplcy&0xff, NULL);
+ }
+ return str;

(Scratchpad stuck in max size "mode")
If my scratchpad is touching any screen border when I restart, ion will forget to write
sizepolicy="free glue" to the saved_layout.lua file, and after restarting it will then
take up the whole screen and not be resizeable. If the scratchpad is not touching any border when
I restart, saved_layout will show the "free glue" entry for *scratchpad* and will
function properly.
