Openrct2: Game closes when trying to make path over map edge with sandbox mode on

If you try to build a path over the map edge, normally the game will give an error message, warning you that you're trying to build outside the map. In sandbox mode however, this check is not there.

If you try to build a path on the edge where the X or Y coordinate would become -1 when sandbox mode is on, the game closes. It doesnt crash or freeze, it just closes.

Steps to reproduce:

1. Make a path using the arrow tools, so with a ghost path being drawn in front
2. Create a path up to the map edge where the x or y coordinate is 0 with sandbox mode turned off (should work fine)
3. Do the same with sandbox mode turned on (game closes)

I can not reproduce this with just sandbox mode, but I can with clearance checks disabled. The crash only seems to happen on the two sides where x = 1 or y = 1.

sandbox mode?
clearance checks disabled?

I'm not sure what this is about.

@Chaosmeister Sandbox mode is a mode that lets you build anywhere outside the park, and adds the functions you have in the scenario editor to the map window.
Clearance checks are checks performed by the game before placing anything, to verify that there is enough space. By disabling those checks (which is a cheat), you can build anywhere.
