using a condition that uses "objectivesComplete" as a test within objectives will cause immediate game crash.

e.g.
{"id":"testObjobjectivesComplete",
"conditions":[{"objectivesComplete":{"value":8}}]
},

"objectivesComplete" is _normally_ used to set and remove locks within triggers, so its use this way is probably caught in some infinity loop, but the game doesn't catch it.
(meaning the mod will load and the Custom Map will play until the Section containing the above is unlocked).
