whenever i try to bonemerge a colored ragdoll onto any npc it give the error:

[Improved Ragdoll Colorizer] lua/includes/extensions/table.lua:87: bad argument #1 to 'pairs' (table expected, got userdata)
1. pairs - [C]:-1
2. Merge - lua/includes/extensions/table.lua:87

is this just an incompatibility or is there a patch for this or?
