In #developer-talk, TankNut and DMatter04 saw props spawning as effects on dev. drobotk said that every changelevel changes which models break, and the helicopter bomb becomes an effect after about 12 changelevels. Darth couldn't reproduce it on the same dev build after 25+ changelevels.

In #next-update, Vitroze reported that after Alt+F4 → Cancel, opening the Problems menu and clicking outside loses focus on the main menu (x86-64 build 10211). Dezlo saw server-created menus not removing properly after cancelling the prompt. Earlier, Drago🐉 noted that closing GMod via Alt+F4 or the taskbar now brings up a confirmation menu.

In #next-update, Redox reported servers where cache/map_pack.bsp stops updating, so new maps load lumps from previous ones until a restart. Rubat said it must be written to disk and may need more error handling, and listed the related log messages. They have to be searched for in console.log with -condebug, which Redox avoids for performance; Cynthia suggested enginespew.

FoxProfef reported that SetupDataTables runs before OnEntityCreated on a Linux server.

In #next-update, Redox reported that voice still randomly breaks on the 64-bit dev branch (build 10205 from 16 Oct). A fullupdate doesn't fix it, and snd_restart fixes it only temporarily.

wrefgtzweve reported that NPCs measure melee distance to an object's center rather than its OBB, so large objects make melee NPCs such as antlions just stand around.

In #lua-help, 0d9b reported that util.JSONToTable turns strings that look like vectors into vectors even when called with ignoreConversions set to true. He asked whether this is intended, calling a JSON parser that mangles the output without an option to keep the original values "a bit useless for... parsing json". Artemking4 said he prefers MessagePack.

a-straight-white-male reported that $seamless_scale breaks the second normal map on WorldVertexTransition materials.

tposse reported glitchy audio when EmitSound plays while a CSoundPatch is playing and both use a DSP preset other than 0. It was closed as a duplicate; tposse asked whether it really is one.

RaphaelIT7 reported that GMODLUA_GetUserType uses a static, non-thread-local buffer for the userdata type name, so threads with different Lua states can clash.
