i found a bug in mania drive, it is not very harmfull and not easy to correct.
Program is looking for story file using the path api, this mean that this story file can be anywhere in the registered path.
After a php script use story file. But the php script run only on local dir.
So story file can be found by raydium api and not found by php scripts.
WorkAround: store story file only in mania_drive directory.
Perhaps we need to add an equivalent to path api in php i'm not sure.
It's a hint for maniadrive 2
Have a nice day
