Why is IGNOUs paper checking so poor? Are they just playing with the students' futures?

Yes. The IGNOU marking system is very poor, and you must have a lot of patience if you are pursuing any degree from IGNOU. If you fail to submit your assignment grades, your results will be delayed for several months.

IGNOU is certainly playing with students' careers because they are so unconcerned about their grades and future. They are unconcerned about how and what is written on the answer sheets. They only postpone things and do not address the issue.
