Dear Maintainer, I tried to have a look at this savegame and when loaded shows these freezes to me too.
An attached gdb shows that leaving VertexPathfinder::ComputeShortPath takes some minutes, while the game is frozen. Upstream might have already some optimizations for this issue in [1]. At least the game shows an "obstacle" that might block some units, because of an closed gate. Kind regards, Bernhard (gdb) bt #0 CheckVisibility (a=..., edges=..., a=..., edges=..., b=<synthetic pointer>...) at /usr/include/c++/10/bits/stl_vector.h:918 #1 VertexPathfinder::ComputeShortPath (this=0x5587684b0f50, request=..., cmpObstructionManager=...) at ../../../source/simulation2/helpers/VertexPathfinder.cpp:786 #2 0x00005587572ccc1d in CCmpPathfinder::PathfinderWorker::Work (this=0x558767340600, pathfinder=...) at ../../../source/simulation2/components/CCmpPathfinder.cpp:772 #3 0x00005587572ccffb in CCmpPathfinder::StartProcessingMoves (this=0x55875e086000, useMax=<optimized out>) at ../../../source/simulation2/components/CCmpPathfinder.cpp:841 #4 0x000055875725417f in CSimulation2Impl::Update (this=0x55875e1350c0, turnLength=<optimized out>, commands=std::vector of length 0, capacity 0) at ../../../source/simulation2/Simulation2.cpp:399 #5 0x000055875729647c in CTurnManager::Update (this=0x55875db87c20, simFrameLength=<optimized out>, maxTurns=1) at ../../../source/simulation2/system/TurnManager.cpp:169 #6 0x00005587573e786e in CGame::Update (this=0x55875bb809d0, deltaRealTime=0.20622983574867249, doInterpolate=<optimized out>) at ../../../source/ps/Game.cpp:400 #7 0x00005587571f3b32 in Frame () at ../../../source/main.cpp:426 #8 RunGameOrAtlas (argc=<optimized out>, argv=<optimized out>) at ../../../source/main.cpp:692 #9 0x00005587571e021a in main (argc=1, argv=0x7fffcf84d8c8) at ../../../source/main.cpp:743 (gdb) finish Run till exit from #0 CheckVisibility (a=..., edges=..., a=..., edges=..., b=<synthetic pointer>...) at /usr/include/c++/10/bits/stl_vector.h:918 VertexPathfinder::ComputeShortPath (this=0x5587684b0f50, request=..., cmpObstructionManager=...) at ../../../source/simulation2/helpers/VertexPathfinder.cpp:786 786 ../../../source/simulation2/helpers/VertexPathfinder.cpp: Datei oder Verzeichnis nicht gefunden.
