In scratch player v33 there is the bug that is that the number items in lists get converted to standart form which uses a few leteers so scratch player thinks it is a string and won't perform numerical operations like add on it. It is badly affecting my project palindromezilla which works perfectly offline as not making into standard form but online it don't work.

Thanks tomhartley - I believe that bug has already been reported to the development team.
