Unable to load xyz files into Selection Info panel when all layers are hidden. Fixed in 1.2.0 1.1.0
MigriBee does not accept longer paths than 200 characters.

Fixed in 1.2.0

Note: The max filepath length on Windows is 256 characters, while Linux has no limit.

1.1.0
Clip planes and planes are clipped to camera. Fixed in 1.2.0 1.1.0
When closing Migri by clicking the "x" button in the upper, the process is not shut down properly. Fixed in 1.2.0 1.1.0
Gridmaps are not loaded when root node is toggled. Fixed in 1.2.0 1.1.0
History grids (Eroded, Sedimentsurface, Temperature.surface, etc) need to use the same AOI (area of interest) as the geometry used in the modelling.  Workaround: use the Migri Explorer to resample these grids and use the resampled grids as input. 1.0.8
Not everything is stored when exporting to VTFx (for Migrino), e.g. wells and streams. Open. Only patience helps here, but do tell us what your highest priorities are. 1.0.8
Maturity plots, including Maturity.windows may be corrupted if you navigate back and forward between timesteps.  Workaround: when using these properties always move forward in time. 1.0.8
The accuracy of the depth geometry model created by Migri and the accuracy of the burial history has been an issue for some users. Burial history accuracy is, in our experience, in the +-5m range for paleodepths and ca 10 cm for the present day depths.  Fix: The 1.1.0 release may in many cases improve the accuracy  if you recreate the history and geometry files. 1.0.8
