Hawkings hooks

mees

I just played a match on hawking where on the strairs leading up to the upstairs area there were no hooks. I was not able to hook the survivors that went down on the top floor. I thought that those hooks were guaranteed and always spawned. I might just be wrong but if not then this is bugged. This was on pc btw although I dont think it would matter. I tried going to hawkings in custom games to take some screenshots but of course now the hooks do spawn. Ive tried like 7 times in custom so i guess its prettyy rare
