"Insufficient Storage Space" problem with Titanium Root, preventing backup
I have no idea what happened, or how, but I had to use a different browsing method for Titatium Backup. Even though I had selected sdcard/titaniumbackup (example), it wouldn't work even though it was listed as an option. I believe I had to use a different backup storage option, in which it showed me a list. After I selected "SD" from this new interface, it fixed everything and now the weird games will backup.
I apologize for this idiocy of mine. Since only one group of games were acting up, I thought it was something of specific conflicting data.
