            <title>[MC-2202] Inconsistent pulse length/delay with torch and repeater combination</title>
                <link>https://bugs.mojang.com/browse/MC-2202</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;In the attached screenshots I&apos;ve build the following circuit four times:&lt;br/&gt;
First a pulser which produces a 3 tick pulse, which is then negated by feeding the pulsar signal into a block with a repeater, on which a torch is attached.&lt;br/&gt;
The torch is used as the output.&lt;/p&gt;

&lt;p&gt;The inner two are exactly the same (block by block) except mirrored (which does not affect the behaviour).&lt;br/&gt;
The same is true for the outer two.&lt;/p&gt;

&lt;p&gt;The difference between the inner and outer is only by placing the negation part one block diagonally away.&lt;/p&gt;

&lt;p&gt;If the pulsar is fed an on signal the following can be noticed:&lt;br/&gt;
1) Although the circuit logic is the same as is the repeater count, the inner ones signal is a tick later than the outer ones&lt;br/&gt;
2) If I place a repeater near the torch the pulse length is changed by one tick&lt;/p&gt;</description>

                            <comment id="50737" author="arokh" created="Thu, 7 Mar 2013 17:58:26 +0100"  >&lt;p&gt;Please check &lt;a href=&quot;https://bugs.mojang.com/browse/MC-2340&quot; title=&quot;Redstone torches schedule updates when they should not, causing unreliable timings.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-2340&quot;&gt;&lt;del&gt;MC-2340&lt;/del&gt;&lt;/a&gt; which probably already describes your issue.&lt;/p&gt;

&lt;p&gt;Yes, that might be the case, I have no way to be sure though.&lt;br/&gt;
I guess I will report it again when that issue is fixed but this one is not.&lt;br/&gt;
So feel free to mark this one as a duplicate.&lt;/p&gt;</comment>
                            <comment id="50733" author="arokh" created="Thu, 7 Mar 2013 17:54:42 +0100"  >&lt;p&gt;After some more investigation:&lt;br/&gt;
Faulty behavior as described in previous comment stays the same until 13w03a.&lt;/p&gt;

&lt;p&gt;The following changes are visible:&lt;br/&gt;
Pulsars which produce one tick pulses work again.&lt;/p&gt;

&lt;p&gt;Pulses with one tick work fine (one tick on all repeater paths)&lt;br/&gt;
Pulses with two ticks are shortened (by one tick) on the outer repeater paths&lt;br/&gt;
Pulses with three ticks work fine (three ticks on all repeater paths)&lt;/p&gt;</comment>
                            <comment id="50730" author="bljat" created="Thu, 7 Mar 2013 17:38:15 +0100"  >&lt;p&gt;Please check &lt;a href=&quot;https://bugs.mojang.com/browse/MC-2340&quot; title=&quot;Redstone torches schedule updates when they should not, causing unreliable timings.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;MC-2340&quot;&gt;&lt;del&gt;MC-2340&lt;/del&gt;&lt;/a&gt; which probably already describes your issue.&lt;/p&gt;</comment>
                            <comment id="50727" author="arokh" created="Thu, 7 Mar 2013 17:33:31 +0100"  >&lt;p&gt;The bug reoccurred with the pre1.5 (or earlier, I only checked pre1.5 for now).&lt;/p&gt;

&lt;p&gt;I had to increase the delays for the pulsars (repeater nearer to the clock) by one tick otherwise no pulses were generated.&lt;br/&gt;
By increasing it by one tick, pulses of two ticks are generated.&lt;br/&gt;
(Bug? Already reported?)&lt;/p&gt;

&lt;p&gt;With that change described above, the two inner repeater paths show two ticks as exprected.&lt;br/&gt;
The other two repeater paths on the other hand show only one tick.&lt;/p&gt;

&lt;p&gt;Can I somehow reopen the issue or should I clone it?&lt;/p&gt;</comment>
