here is a description about the bug when trying to write briefing in English.
in the RSE file we write:
BRIEFING_MESSAGE50,This is a pen.
the program will show:
the "is a pen." part will be missing.
Our programmer told me that it's because RSE recognizes the common english keyboard "space bar" (半角スペース?)as a terminate sign for a line of command. This is not a bug for japanese because japanese sentence won't use this. But when you write english, which uses space between every word, it terminates the line of command after the first word.
Furthermore, there is a bug regarding the "setsection 30"(helicopter propellar).
I built a helicopter with a child object propellar(toybox). Then I set the helicopter as an enemy. After shooting it down, strange things start to happen: When you fire missiles, guns, or catapult any object from L1, you will randomly see a propellar sticking on it and flies all over the battlefield. This happened in 3.11b.
