If you try to add new location or field item in 1.5.1, it will always crash at saving
I add the model in the model loader, add one animation for it, then add the script, save -> CRASH
doing the above via importing a field works fine though
ALSO
some fields are very, very allergic to being altered in MR. In some cases, adding field models to a field will cause the scene to break. some earlier field models will vanish ( adding locations seems to work )
I tried to change script in ealin_12 but it broke the whole scene
I'm not sure what exactly causes this
in 1.5.1, if you import a normal field file ( not a decompressed one ) it doesn't update the model loader. I can't tell if it's because it doesn't export right or doesn't import right.
