encountered no, I rarely export animation with a decimal in the line multiplier on my pc 
So yeah, I tried, french version too, same problem.
I wonder if it relates to the classic decimal point on some non english version problem.
The line multiplier field still expects a decimal dot even if your computer is in non english (or american) parameters.
However, it won’t accept shift + ; to place a dot. it expects you to use the numpad decimal key.
If you don’t have one, you’re done. if you’ve remapped it to force a comma (as I did), you’re done.
(I also tried typing 0.5 elsewhere and pasting it but the field really don’t see key combinations)
I guess it would be an easy fix, simply have the field use the decimal symbol of windows and not the american dot.
ping to @colin who is probably eating turkey leftovers this weekend, so he can pass it on
