Segmentation fault when pressing 1 or 2 to select demo simulation

[clausagerskov]

after running build.cmd (ow-0.9) on Windows Docker with WSL 2 and running ./Release/Sibernetic, and pressing 1 or 2 when Sibernetic is running results in a segmentation fault.

[clausagerskov]

using valgrind to get diagnostics returns the following:

[clausagerskov]

can confirm this happening on an Ubuntu machine, a Windows machine (compiled using Visual Studio 2019), WSL2 on same Windows machine, as well as a docker image, all running either ow-0.9 or newest version of Sibernetic

[clausagerskov]

when debugging on windows 10 x64 line 327 in owHelper.cpp has an acess violation:

[clausagerskov]

this actually seems to happen with all shortcuts that change or load config files like "r", "1", and "2". could be that some variable is not initialized properly

[clausagerskov]

found the issue, someone removed this command: owHelper::preLoadConfiguration(config);
from owPhysicsFluidSimulator::reset() right before config->initGridCells();
Readding it restores the button 1 and 2 demo functionality
