I took the following steps:
- opened map
BPRockB.cmap (at cmap version 13) in CaWE,
- copied (Ctrl+C) the
- pasted (Ctrl+P),
- saved (at cmap version 14).
As expected, there were two
weapon_facehugger entities in the map, but the second had the exact same name as the original.
Consequently, any attempt to re-load the map failed with this error:
Warning: Could not load "Games\DeathMatch\Maps\BPRockB.cent": Games\DeathMatch\Maps\BPRockB.cent:288: bad argument #1 to 'AddChild' (child entity already has a parent, use RemoveChild() first)
It was expected that pasting the entity checked its name, and adjusted it accordingly to avoid duplicates!
