FreedroidRPG 0.16-410-g7d8504e_mod encountered a problem in function:
CheckForTuxOutOfMap
A player's Tux was found outside the map.
This indicates either a bug in the FreedroidRPG code or
a bug in the currently used map system of FreedroidRPG.

...

FreedroidRPG will terminate now to draw attention to the problems it could
not resolve. We are sorry if that interrupts a major game of yours.

Termination of freedroidRPG initiated... Thank you for playing freedroidRPG.



After uploading the firmware the bots died.
As I was sweeping the maps to pick up leftover drops I ventured into the area
after the Swap for the first time.
The crashed happened while I was running next to the shoreline.

Thanks for the report
Will Try to take a look at it tomorrow

Given the player's position (X=-0.000002), I suspect a floating point arithmetic
error when the 'virtual player position' is resolved during the level boundary
crossing.

A patch, which should prevent the reported crash, has been pushed in commit
dade2a74c.

Reopening - dade2a74c70808f7b4bb86604e4ba11004946cbe introduces crashes when zooming out 9x and looking on the side of level 0.

Rework the first patch, with a better workaround, in commit 692a9db5b.
