Clicking the hull-left conveyor belt on the GeoCorp harvester in the "conveyor bug" save causes the game to lock up indefinitely about a second later. If I disassemble the belt completely and then reinstall it, it seems to work fine unless I save and load the game, after which the error occurs again. Saving the harvester as a snapshot, sending it to inventory, and then respawning it causes the bug to happen as well. Happens every time except for when the belt is removed and replaced manually, and even then the error returns after saving and loading. The error was discovered in campaign mode, but occurs in R&D as well if the tech is loaded. I do not know what exactly precipitated this bug while designing the tech; I was trying to find an optimal way to pipe resources from the front to the back to be dropped on a collector pad (please, please just let us directly push/pull from conveyors to collectors somehow!) when I noticed that the left belt had some conveyor blocks moving in the opposite direction as the rest. When I clicked the belt to try correcting this, the game locked up. Unfortunately I didn't think to save the game while the belt was in that mixed-up state before TerraTech froze, but the locking up part is easily reproduced by clicking the belt. edits: Added snapshot Replaced picture indicating which belt with a picture showing the belt after clicking it, with the first conveyor block in the line (starting at the receiver) moving in the wrong direction relative to the rest of the belt. This picture was taken after loading the game, removing the belt, rebuilding it, saving the game, then reloading the game from the new save and clicking the belt to reverse the flow and produce a lockup.
