The map I was building is destined to be an XD race map, which states in its rules that the maps must not be uploaded or given to anyone other than riolu before the race. I didn't want to breach that by giving you the map, so I was pondering whether to give it to you or not for a while. At this point I had stopped mapping overall, so I kind of forgot about all this.
However at some point I wanted to try and build a multi-lap version of valley A08. I did so but when I saved the map and tried to calculate the shadows, I had the same DEVICE_HUNG error and now whenever I try opening this map, the game just crashes. I sent the map to a friend, he can open it perfectly fine, so I asked him to place another block/replace one and save it to send it back to me. I haven't yet opened the map as I don't want it to be corrupted by me opening it, though I'll open it as soon as I sent this message to see what will happen.
Here is a link to both of the maps, aaaaaa08 is the unmodified version that crashed on me, while aaaaaa08modified is the version my friend sent back to me after modifying it.

I also got the issue while driving once ?? It was during the first race of the second season of riolu's XD race (you can see me complaining in chat

I hope you can make something out of this but I'm not sure you will since the issue is most likely on my side.
Thanks niebo for reminding me
