| Summary | 0000849: Crashbug with Lua-spawned units | ||||
| Description | In KP.net I sometimes get a crash with the Network's Dispatch command. The command spawns units in a ring around another unit and gives them a move order. Sometimes this move order crashes the game. It's the easiest to produce if you use WIP2: Spawn 4 network_big with one give command and don't move them. Spawn 48 network_spam, select them and rightclick onto one of the big units from before (preferrably the closest one so no bumping happens). Once all spam has disappeared with those white flashes, select all four big units, click on dispatch and then on any place on the map. BAM, crash. Works in both 76b1 and SVN. | ||||

when it happens in a multiplayer game all players crash simultaneously. |

I've made the Lua script verbose and GetUnitPosition works fine, reports the numbers it should. Well, the units show up fine too and start moving just fine, only a moment later does it crash... |

I think I fixed it in r5518, there was a division by the length of a vector difference in the collision code, if two units had the exact same coordinate that would cause a division by zero. |
