Large field count causes settings to be wiped out

When dealing with a node type that has upwards of 100 fields, workflow fields and workflow 1.2 seems to wipe out the field checkbox page upon submit. I had various workflow steps with numerous fields checked for different roles both visible and editable, and upon submitting it wipes out all but about 60-70 field settings. The only way for me to fix the issue was to manually set the mysql database field values, which will get read properly when visiting the field settings page, but upon submit it wipes out all the settings to not checked.
