Game version:

Operating system:
WinXP

Tiles or curses:

Mods active:

Expected behavior

Shows the actual time to complete crafting/construction

Actual behavior

Steps to reproduce the behavior

Open the crafting or construction menu

Notes:
Searching for "for ever" in the source and comparing it with an older version (7426) without this problem leads me to this. The actual time to craft the item works as intended though, only the UI says it will take "for ever".

What was your morale at for the screenshot, in consideration of #23299 ?

[budg3]

+66 but I also tried it with a new character at the starting morale with the same results.

Possible cause: Change code in to_string(time_duration) to use time_duration functions

Probably wrong sign: < instead of >.
