Hey I'm currently using pk3DS build 200 (tested 197 aswell) and am unable to open "Wild Encounter" with a dump of my own digital version of sun (v1.0) from gm9.
Everything else appears to work as intended.
Windows 10 x64 LTSB
Error in spoiler
Edit: updating .net
edit2: nope, trying another win10 machine I have
edit3: same error on another regular Win10 x64
I will try and redump
