I've made a simple custom fluid which overrides it's tick method in order to run some checks for any nearby burning blocks. Using the debugger and some breakpoints, I'm able to see that while the tick method for FlowingFluid is being run, my method which overrides that one isn't.

Could you show some of your code?

public abstract class NitroglycerinFluid extends ForgeFlowingFluid {
    // Directly reference a log4j logger.
    private static final Logger LOGGER = LogManager.getLogger();

    protected NitroglycerinFluid(Properties properties) {
        super(properties);
    }

    public static Properties createProperties() {
        return new Properties(() -> ModFluids.NITROGLYCERIN, () -> ModFluids.FLOWING_NITROGLYCERIN, FluidAttributes.builder(new ResourceLocation("sussybakaplus:block/nitroglycerin_still"), new ResourceLocation("sussybakaplus:block/nitroglycerin_flow")).overlay(new ResourceLocation("sussybakaplus:block/nitroglycerin_overlay")).density(3000).viscosity(1000).luminosity(15).temperature(1300)).tickRate(1).canMultiply().bucket(() -> ModItems.NITROGLYCERIN_BUCKET).block(() -> ModBlocks.NITROGLYCERIN);
    }

    @Override
    public boolean isSource(FluidState state) {
        return false;
    }

    @Override
    public int getAmount(FluidState state) {
        return state.getValue(LEVEL);
    }

    public void animateTick(Level p_76445_, BlockPos p_76446_, FluidState p_76447_, Random p_76448_) {
        LOGGER.info("animate");
        if (!p_76447_.isSource() && !p_76447_.getValue(FALLING)) {
            if (p_76448_.nextInt(64) == 0) {
                p_76445_.playLocalSound((double)p_76446_.getX() + 0.5D, (double)p_76446_.getY() + 0.5D, (double)p_76446_.getZ() + 0.5D, SoundEvents.WATER_AMBIENT, SoundSource.BLOCKS, p_76448_.nextFloat() * 0.25F + 0.75F, p_76448_.nextFloat() + 0.5F, false);
            }
        } else if (p_76448_.nextInt(10) == 0) {
            p_76445_.addParticle(ParticleTypes.UNDERWATER, (double)p_76446_.getX() + p_76448_.nextDouble(), (double)p_76446_.getY() + p_76448_.nextDouble(), (double)p_76446_.getZ() + p_76448_.nextDouble(), 0.0D, 0.0D, 0.0D);
        }

    }

    @Nullable
    public ParticleOptions getDripParticle() {
        return ParticleTypes.DRIPPING_WATER;
    }

    @Override
    protected void beforeDestroyingBlock(LevelAccessor accessor, BlockPos pos, BlockState state) {
        BlockEntity blockentity = state.hasBlockEntity() ? accessor.getBlockEntity(pos) : null;

        LOGGER.info("spread to " + state.getBlock().getRegistryName().toString());

        if (state.getBlock().getRegistryName().getPath().equals("fire")) {
            float f = 4.0F;
            Minecraft.getInstance().level.explode(null, pos.getX(), pos.getY(), pos.getZ(), f, Explosion.BlockInteraction.BREAK);
        }

        //Block.dropResources(state, accessor, pos, blockentity);

        } else {
            LOGGER.info(pos.toShortString() + " doesn't have any buring neighbors");
        }
    }

    private boolean hasBurningNeighbors(LevelReader levelReader, BlockPos pos) {
        for(Direction direction : Direction.values()) {
            if (this.isBurning(levelReader, pos.relative(direction))) {
                return true;
            }
        }

        return false;
    }

        return (pos.getY() < levelReader.getMinBuildHeight() || pos.getY() >= levelReader.getMaxBuildHeight() || levelReader.hasChunkAt(pos)) && levelReader.getBlockState(pos).isBurning(levelReader, pos);
    }

    protected float getExplosionResistance() {
        return 0.0F;
    }

    public int getTickDelay(LevelReader p_76226_) {
        return p_76226_.dimensionType().ultraWarm() ? 1 : 1;

My Fluid Class

I fixed it by making a liquidblock for the fluid, which I didn't do (correctly).

Additionaly, I made the class extend FlowingFluid instead of ForgeFlowingFluid.

Can you share your items/blocks registries and the class fixed? please :C

you need to create your own LiquidBlock, copy the vanilla code and replace all code which use the vanilla Field with LiquidBlock#getFluid
