Uberfletch freezes

[Jennyfer]

Looks like on line 2237 is the cause of the freeze to me but I don't know how to fix it. I attached the full section of code that is involved in that line.

You remove a black imflass dagger from in your leather longcoat.
>
Using your previous mark as a guide, you cleanly slice the end off the arrow shaft.
Roundtime: 4 sec.
R>
You put a black imflass dagger in your leather longcoat.
>
You remove a bottle of fletching glue from in your leather longcoat.
>
You carefully smear a bit of glue on the arrow shaft.
Roundtime: 15 sec.
R>
You put a bottle of fletching glue in your leather longcoat.
>
You reach for a bundle of fletchings and remove 3 of them.
>
You attempt to attach some fletchings to the arrow shaft, but they refuse to comply, falling off time and again, until the glue is too dry to work with. Luckily, you are able to salvage the shaft.
Roundtime: 21 sec.
