AutoNewline - 0x2026E30
Amount of space used is variable, since it copies textIDs there for processing. Location can be changed in installer.event
ArenaLimits - 0x203AAC0
Amount of space used is also variable, since it copies user defined text strings there (but only a couple sentences, so far less than AutoNewline). Location can also be changed in installer.event
