GZDB Bugfix possible bug, can't set negative Movement speed for Polyobj

[snapshot]

Whenever I enter a negative value for movement speed (eg : -16) GZDB automatically resets it to 0 (ZDoom in Hexen Format) although it works fine in UDMF Format, is this some sort of bug ?

It's not a bug I think. Hexen format stores argument values in unsigned type while UMDF uses normal signed integer. So you cannot have any negative values in linedef arguments in hexen format

So I can't move it to opposite direction without having to change to UDMF ?
EDIT : nevermind, silly me I just have to change the angle instead, thx.
