That's unfortunate. That said, the rules specify that reloading the save will disqualify the run. Generally speaking, runs should be one recording, not multiple. Under these circumstances, your run would be allowed to be submitted to the 250, 500, & 750 room catagories if there were no reloads prior, but it would not be valid for the 1000 room catagory.
Hey there. Not a mod, but generally speaking reloads are disallowed due to the risk of save scumming, since room RNG is a notable factor of each run.
Out of curiosity, what do you mean by you 'couldn't continue further'? Did you encounter a bug of some sort?
If anyone happens to be looking at this for whatever reason, I just want to make note of the fact that this is likely the fastest run that had been performed on what was at the time, current patch. This was done without downpatching, and I am extremely proud of what this run was.
Well that was a fast replacement of the last record LOL gg!
