This is the fixed vine arrow model for Thief 2. The original one is buggy and not rendered properly. Open your  Thief2/Res/obj.crf with Winzip and add "arrowvin.bin" from this archive to replace original model or in your 
Thief 2 folder create "obj" folder and put the model there. This will overwrite the original one. Don't forget to include the fix in your FM so other taffers could see it.
