Would appreciate it if you could put some dummy checks into the code that will prevent a game crash should I do something stupid like this again. Not fun to lose the progress I've made since my last auto-save and it could cause issues if this were to be taken advantage of by griefers in multiplayer. I push CTRL + ALT + LEFT CLICK at the same time when clicking on the blueprint icon with my blueprint, but other combinations might also cause something similar.

Error message:
The mod Logistic Request Manager (continued) (1.1.17) caused a non-recoverable error.
Please report this error to the mod author.

I just did it again, this time was CTRL + V. Yup, that's right, paste. I was hovering over the blueprint drop icon again and wanted to bring up the blueprint I had just copied in order to request it. And WAM! Error as follows:

The mod Blueprint logistics requests (1.0.1) caused a non-recoverable error.

Hello NightOps,

sorry you lost progress.

I'll look into it as soon as I can.

Do you have any noteable mods active that I should double-check?

That's another mod. Not LRM.

Ah, woops. Didn't pay enough attention to the mod causing it and immediately posted based on the fact that I was interacting with LRM at the time. Weird that it happened while using LRM though. I wasn't actually doing anything with the other mod at the time.
The notable mods I'd say are space-exploration & Krastorio2, being the two big ones.
As for the complete mod list:
"base", "aai-industry", "aai-programmable-structures", "aai-programmable-vehicles", "aai-signal-transmission", "aai-signals", "aai-zones", "Actual_Craft_Time", "AF-Infinite-Technology", "alien-biomes", "Armor_pockets", "assault-rifle", "assemblyanalyst", "AutoDeconstruct", "BatteryVehicleDisplay", "BetterBotsFixed", "Better_Asteroid_Mining", "blueprint_flip_and_turn", "Bottleneck", "bullet-trails", "ClosestFirstOneDotOne", "combat-mechanics-overhaul", "Configurable_Fuel_REUPLOADED", "DeathMarkers", "DoubleSpeedBelts", "Enhanced_Map_Colors", "epic_mining_and_crafting_speed_research", "equipment-gantry", "even-distribution", "Factorissimo2", "FARL", "Fill4Me", "flib", "fluid-void-extra", "Fluidless_Mining_and_Ore_Washing", "hazmat-suit", "inbuilt_lighting", "Infinizoom", "informatron", "inventory-repair", "jetpack", "KingsTurret-Shields", "krastorio-nuclear-fuel-compat-updated", "Krastorio2", "Krastorio2_BioLabModules", "Kux-OrbitalIonCannon", "LogisticRequestManager", "Max_Train_Brakes", "Moar-Radar", "module-requestor", "more-minimap-autohide-017", "Nanobots", "NextGenEvolution", "no-wall-repair", "NoRespawnGun-Updated", "Noxys_QuickerStumpFade", "Nuclear Fuel", "Personal-Roboport-Mk3", "railloader", "RateCalculator", "resourceMarker", "reverse-factory", "robot_attrition", "SchallEndgameEvolution", "SchallUraniumProcessing", "Shield-FX-Updated", "Shortcuts-ick", "show-max-underground-distance", "smr", "space-exploration", "space-exploration-graphics", "space-exploration-postprocess", "space-factorissimo-updated", "SpawnControl", "Squeak Through", "stdlib", "there-is-my-ghost", "Todo-List", "TrainSpeeds", "Transport_Drones", "tree_collision", "Turbwhine", "useful_equipment_bump", "VehicleSnap", "Vehicle_Radar", "VisionRadar", "VoidChestPlus", "vtk-armor-plating", "walkable-beacons", "walls-block-spitters", "WireShortcuts", "ZElectricVehicles", "zk-lib"

I found the culprit for your first post.
Will be fixed in the next release.

Awesome! Thanks.

I just pushed the update to the portal.
