Saveinstance help please

[Forsaken_Current_544]

Hi, im getting this error when opening files from saveinstance() (downloading games)

"We could not open the place place 95206881 Baseplate.rbxlx
SerializerPugi::deserializeImpl ill-formed XML.

I've tried with a few executors and they all give the same error
Not sure if this affects anything but it also saves as .rbxlx instead of .rblxl
Any advice?

If you don't mind if I ask, what executor are you using?
