I tried exporting three areas to be used in my module from the Witsend prefab by rjshae (really beautiful areas by the way) https://neverwintervault.org/project/nwn2/prefab/area/witsend , but when exporting as an erf I got the error:
System.FormatException: Input string was not in correct format…
I saw an old thread where something similar was adressed:
However, when importing the erf and opening the areas in the toolset in my mod, and then trying it out in game, everything seems to be working just fine. Do I need to worry? Should I not be using this? Will there be problems later on perhaps?
