OpenXcom requires a vanilla version of the original UFO: Enemy Unknown / X-COM: UFO Defense (any edition) with the latest patch. It is not compatible with other games in the X-COM series. If you don’t own a copy, you can buy it from one of these retailers.
Do not use modded versions of X-COM, as they may be incompatible with OpenXcom.
Check the Installation documentation for more details.
These builds are automatically generated from the codebase, so they have the latest fixes and updates as well as the latest bugs. Use these to try the latest features or check if a bug is obsolete. Do not install these on top of 1.0!

Fix crash if you save and reload during a multi-part mission, such that items recovered in one stage conflict with items spawned in the next stage, and if an explosion removes one of the conflicting items, causing a segmentation fault when the memory is cleaned up when the mission ends / reloads.
