Spring RTS Engine

Whe I play a singleplayer game, and it last 1 hour maybe few minute more, it appears this message:

[f=0132810] Error: LuaUI::RunCallIn: error = 4, Update, not enough memory

At the same time all the widgets get disable, and I have tried to enable them pressing F11 but I can´t enter to the widget menu.

... that's not good.

As a workaround, open the chat console and type
to force a reload of the luaui system. That should free the memory.

Thanks! that works.
