String breaking issue

[Scatterbass]

Or at least it has the potential to become one. I've been playing bass for some 18 years and have never had this problem till recently.
About a month ago I broke my E string at a show. Thankfully it was the end of the night with only 5 songs left. I have a 5 string so I could still finish the night. The strings were DR Marcus Miller sig. series and they were about 4 months old.
I replaced them with Darcos (mainly because I was to broke to get better strings lol), Anyway, they are only about a month old and I broke the E on them too. Both broke at the saddle (and when I say broke, I mean the core broke and they came unwound).
I play on an old 97 Washburn. I checked the saddle for burs or anything that could cause it, but found nothing. We play primarily 440 dropped a half step.
Thats all the info I can think to give.

Guess no one knows anything about bass issues on here lol

Stringing thru bridge or thru body?

There's a sticky that says you need to check out a bunch of links before posting... and this is covered there. Could be a saddle spur, your playing style, or also the DR string construction because I have found unless those round core strings are installed perfectly they are bad about breaking.

I did a search but found nothing to match what my problem was. Not to say I overlooked one, I just didn't see it.
It's a bridge thru
I took it to a repair shop and he found the problem I seemed to have missed a bur on the saddle. I'm putting string savers on it to remedy the issue from happening again
