the problamo is that he has to many mods

Crashing when? When he spawns a bomb? Loading the game? Details like these are much needed when trying to get a solution.

When the mod is installed and when he opens the game the game instantly crashes

Also he dosent have many addons,he has like 10-11 addons

i have no clue, it doesn't do this with anyone else

Alright,so he recently validated files and it fixed it,i have a feeling Hbombs deleted some of his files.

That's impossible. Addons can not delete files.

Well i dont know then :/. At one point when he tried to start gmod (after validating files) he seems to be still crashing :/

Is he completely sure it's hbombs? and not one of the other eleven addons he has? Tell him to enable only one addon at a time, to see which one crashes. Also, since there are so few addons you said, can you tell him to list them all for me? Maybe it's a conflicting addon.

some addons clash and this may interfere with something your friend has. even though it might seem unlikely, alot of mods here clash with others. gbombs, wac, neuro, hvap, they all clash with every thing.

HBOMBS does work with Gbombs 5 and WAC and I know this to be true. As for Neurotec, hvap, and gbombs 4, I know won't work.

So what your trying to tell me that Hbombs isnt compatible with Gbombs 4? If im right i think i found the solution

It's not compatible with Gbombs 4.

Thanks for the support,ill tell him to disable/deinstall gbombs 4!
