Ever since installing the so-called "weapons pack" by Vega, the Kh-23L (didn't test the R so far) acts a bit FUBAR, at first sight the launches are totally random, sometimes the missile disappears, sometimes it appears. Really weird stuff - like - you press launch button fourtimes, two missiles on right disappear, two last actually fly to the target. Then you press it once more, third missile flies towards the target, but you still have two missiles under your plane - this time even on the opposite side o.O Then I launched one more (fourth of four), but when I accidentally hit the button once more, it did not tell me that there was no more missiles, but instead, it told me about the next missile not being ready - meaning there had to be at least one more (next thing I remember was me crashing into ground, sadly).
Also, S-8's have quite big dispersion...
Tested with last Su-25 + MA 5.3
