You better search for real reason that got you banned, because it's not for using my modpack. It's officialy checked and allowed modpack. Contact WG about it.
This particular problem has started to occur just recenly, in 7.0.0. I was talking with Haka since he has more experience in modding panels, and he told me what I told you before. Maybe it will be fixed by authors of that Panels in future who knows. Real authors are Badobest and Roslich. Haka is only making changes using their mods as a base.
