I would still bet that users having a reboot at speed failed to copy the transportm.ttf to apl2\igo.
Anyone with the issue, verify the file is there and possibly copy a fresh one to the folder.
Most of my scripts were stolen from GTIMatt's newest version and I'm not having anyone report reboot at speed issues.
I did NOT use his custom font for my speed limit signs, though.. Just to avoid this problem. It is prettier, but wasn't worth the risk to me.
Nice catch, I'll make those changes in my data.zip (although spr_battery should exist because I never bothered commenting it out of navigatemap_800_480).
I did remove the reference to that battery sprite in my nm8x4 and it led me to find the other 2 lurking in browsemap.
There is still a mini-battery sprite in nm8x4, so the other was pointless. It is still safe to comment it out in browsemap if you already have, regardless.
