Godbert: Can't export MJIStockyardManagementTable (non-integer keys?)

[kotarou3]

When trying to export MJIStockyardManagementTable to CSV with Godbert, it crashes with the following error:

Meanwhile the only data written out as CSV is this:

key,0
#,Material
int32,MJIItemPouch
0

MJIStockyardManagementTable is somewhat unusual in that its keys aren't integers, with keys looking like "0.0" and "3.9". Perhaps that's causing the error? Unfortunately I don't have a C# dev environment set up to debug this any further
