[2019] Devs are lying about SSD spawns?

Let's see some things from patch notes:

Husks now spawn correctly on all Storm Shield Defense waves. 

Note: We discovered that this bug was blocking valid Husk spawn points, now some amplifiers will be attacked from new directions.

Well, first of all, the bug from the first point, started in the end of season 8 to 9 (husks not spawning), never happened before, so, if you use logic, the spawns started beeing blocked when the bug started right? So, until season 8 arrives, everything was working well for 2 years, ok, but, why when you watch YouTube vídeos of ppl doing Twine SSD 10, was always that way, there is something wrong i think, so, devs, are you lying?

Let's remember the Last 3 weeks, there was a glitch that happened on twine SSD, where you was able to make all spawn points not work, using the "pyramid" build, people made Full endurances without any work, pure afk. So, for me looks like the devs got angry about that and decided to punish EVERYONE because of this glitch, and, yes, a glitch it's their fault, just to remember. And well, i'm not saying this is the truth, maybe it was a bug, a 2 years old bug, maybe, but for me looks more like they are acting like angry childrens that hate us, if you devs will going to act like that, we will going to start to.

I Hope i'm wrong, i hope this is just bug problems, but don't looks like.

What you guys think? Are they being honest with us?
