I been doing research on this exact issue for 24 hours and it's a wide spread issue. Tons of people need to use a party system that works with mk summon and they can't find one that works. This is the first one I was able to locate in 24 hours. There's even other pages with summoners plug ins that visu Stella breaks. It's not even just yours. It brakes many summon plug ins. It's a wide spread issue.
