Cheers etmoonshade - you explained it much more succinctly then I did! Guess if Science Alert's just calling a Stock Collect All function for all Science Storage parts: I'm assuming maybe Squad changed the implementation in v1.9, which is causing it to break the basic rule of no duplicate Science stored in parts (just EVA Kerbals)? I checked my Mun Station: Collect All via mod still pulls many duplicates into the Bigby Workshop (as I first found in v1.9), leaving one copy in the penultimate part all the Science is pulled through - think I've probably used manual EVA or Experimental Science Container's PAW in paranoia since! Agreed: bit random but certainly more Science Storage parts then much more likely to find this, but I'm sure a Mun Lander (Can with Experiment Storage) hasn't experienced Collect All issue so far. Will also take a proper look at what's causing this, made my KSP tuition with brother even more complex - but at least if root cause is mix of mods (rather than Stock issue): his limited utility installs has certainly whittled down my long list of culprits to more manageable amount to isolate with!

This is such a must-have quality-of-life utility mod, much thanks to all behind it! Starting to see weird behaviour & Null Ref Exceptions recently (after last update), probably just a mod conflict issue with my install - wondering if anyone else has seen: 1. Minor issue with Indicator not picking up a selected port, seems selecting another port then the original again updates the UI (was blank previously - but can dock with port, so assume must be classed as compatible) 2. Continuous Null Reference Exceptions (see example from log below) while Docking Alignment UI is open from Toolbar - just happened after I un-docked a stock Pod with Wild Blue Industries' MK2 Docking Port, from a station with KerbalMax Industries' Telescopic Clamp-O-Tron Docking Module. I'm assuming this is a new issue, as I used a previous version of Docking Port Alignment Indicator to dock this pod in the past few weeks: [EXC 21:13:58.583] NullReferenceException: Object reference not set to an instance of an object NavyFish.DockingPortAlignmentIndicator.isCompatiblePort (ModuleDockingNode targetPort) (at <713e0ebbc7204aec862c78762bb4afee>:0) NavyFish.DockingPortAlignmentIndicator.determineTargetPort () (at <713e0ebbc7204aec862c78762bb4afee>:0) NavyFish.DockingPortAlignmentIndicator.Update () (at <713e0ebbc7204aec862c78762bb4afee>:0) UnityEngine.DebugLogHandler:LogException(Exception, Object) ModuleManager.UnityLogHandle.InterceptLogHandler:LogException(Exception, Object) UnityEngine.Debug:CallOverridenDebugHandler(Exception, Object) I'll make sure to keep the full log files for when this happens again to help mine / anyone else's debugging (restarted & wiped it... whoops!)

@SkiRich I think your dMagic mods need updating to work with last Science Alert from 1.9.8.7 onwards (see last quote below):

Much thanks to LGG for yet another excellent mod, plus community here supporting all our space races! Just wondering if anyone else has found duplicated science, from using Collect All feature for Science Alert in KSP 1.9 & 1.10? Know it's calling stock command from PAW for science storage parts - seen Collect All in the mod, create identical copies in each part the science is passed through (listing in log top-left), storing these multiples copies in a final science storage part. Not noticed it before, but since KSP 1.9 have spotted this - first with 650 copies of science stored in a Bigby Workshop, assuming due to (lots of) mods conflicting or corruption. But also with very few mods (just other Science like Kraken & dMagic, US2 plus utility / quality of life like KAC & Engineer) when helping brother with his first Kerbin Station, which also had 7 Science storage parts inserting the same number of identical copies into an MPL (just repeated identical steps again a day later, after checking everything's up-to-date). Before pulling logs & files from his install (or using a single part's PAW to Collect All instead), thought best check if I've overlooked something when playing - plus searching around and reading this thread!
