This is a bit hard to reproduce without making a mod that adds a bunch of faction classes. You can simulate it a bit if you've got a lot of mods loaded:
```
// Simulate fn_initModules
biGrps = [];
{
private _group = creategroup sidelogic;
biGrps pushback _group;
} foreach ((configfile >> "cfgfactionclasses") call bis_fnc_returnchildren);
// Simulate someone placing lots of modules
myGrps = [];
for "-" from 0 to 99 do {
private _group = creategroup sidelogic;
myGrps pushback _group;
};
diag_log format ["Simulated fn_initModules groups: %1", count biGrps];
diag_log format ["Simulated module groups: %1", count myGrps];
diag_log format ["Total groups created: %1 / 288", count (myGrps + biGrps)];
```
