For those who are interested, I've uploaded a modified RCCE 2.0 version on the french RC forum: RCCE version 2.0 (200mo)
Everything is working well, except the Water plane bug (I'm still working on it): _ When you create a new map in the GUE, you MUST create a water plane (even if you don't need it on your map, you can scale it down and hide it under your map) or you will have a MAV.
I know the problem and I'm still looking for fixing it.
Thanks for keeping me informed about eventual bugs.
You're welcome Unseenghost. I hope it will help people to continue to work with RC. I'm still working on improving the engine (for instance, I have added chat tabs, thanks to Clan_fd) and I hope I could release a new version soonly
